Chip-Firing And A Devil’s Staircase  

E-Print Network (OSTI)

The devil’s staircase – a continuous function on the unit interval [0,1] which is not constant, yet is locally constant on an open dense set – is the sort of exotic creature a combinatorialist might never expect to encounter in “real life.” We show how a devil’s staircase arises from the combinatorial problem of parallel chip-firing on the complete graph. This staircase helps explain a previously observed “mode locking ” phenomenon, as well as the surprising tendency of parallel chip-firing to find periodic states of small period.

THE DEVIL’S STAIRCASE DIMENSIONS AND MEASURE-THEORETICAL ENTROPY OF MAPS WITH HORIZONTAL GAP  

E-Print Network (OSTI)

Abstract. This work elucidates the measure-theoretical entropy and dimensions of a unimodal map with a horizontal gap. The measure-theoretical entropy and dimensions of the Ft (which is defined later)are shown to form a devil’s staircase structure with respect to the gap size t. Pesin’s formula for gap maps is also considered. 1.

Commensurate phases, incommensurate phases and the devil’s staircase  

E-Print Network (OSTI)

Modulated structures with periods which are incommensurable (or high-order com-mensurable) with the basic lattice are quite common in condensed-matter physics. The structure may be another lattice, a periodic lattice distortion, a helical or sinusoidal magnetic structure, or a charge density wave in one, two or three dimensions. This review surveys recent theories on the transition between commensurate (C) and incommensurate (I) phases, and on the properties of the ‘incommensurate ’ phase. The predictions of theories will be compared with experiments. The CI transition is usually described in terms of wall, or soliton, formation. The nature of the transition and the structure of the I phase are quite different in two and three dimensions. In three dimensions the I phase seems to consist of an infinity of high-order locked C phases, which may or may not be separated by an infinity of truly incommensurate phases. This behaviour is known as the ‘devil’s staircase’. In two dimensions the incommensurate phase (at T # 0) is a ‘floating ’ phase without complete long-range order, and it does not ‘lock-in ’ at high-order commensurate phases. Phase diagrams are determined by the stability of two types of ‘topological ’ defects: walls, which destabilise the C phase with respect to I phases, and dislocations or vortices which generate paramagnetic or fluid phases. A consequence of this competition is that for sufficiently low order of commensurability the C and I phases are separated by a fluid phase. The properties of modulated systems can be studied by iterating certain area-preserving two-dimensional maps. Very recent studies indicate that, in addition to C and I phases, there are chaotic structures which are at least metastable. The chaotic regimes separate C and I phases and may be described as randomly pinned solitons. The relevance of the chaotic regimes to adsorbed monolayers, pinning of charge density waves, Peierls transitions and spin glasses is briefly discussed. This review was received in July 1981.

On the entropy devil’s staircase in a family of gap-tent maps  

E-Print Network (OSTI)

To analyze the trade-off between channel capacity and noise-resistance in designing dynamical systems to pursue the idea of communications with chaos, we perform a measure theoretic analysis the topological entropy function of a “gap-tent map ” whose invariant set is an unstable chaotic saddle of the tent map. Our model system, the “gap-tent map ” is a family of tent maps with a symmetric gap, which mimics the presence of noise in physical realizations of chaotic systems, and for this model, we can perform many calculations in closed form. We demonstrate that the dependence of the topological entropy on the size of the gap has a structure of the devil’s staircase. By integrating over a fractal measure, we obtain analytical, piece-wise differentiable approximations of this dependence. Applying concepts of the kneading theory we find the position and the values of the entropy for all leading entropy plateaus. Similar properties hold also for the dependence of the fractal dimension of the invariant set and the escape rate.

Electron Climbing a 'Devil's Staircase' in Wave-Particle Interaction  

SciTech Connect

Numerous nonlinear driven systems display spectacular responses to forcing, including chaos and complex phase-locking plateaus characterized by 'devil's staircase', Arnold tongues, and Farey trees. In the universality class of Hamiltonian systems, a paradigm is the motion of a charged particle in two waves, which inspired a renormalization group method for its description. Here we report the observation of the underlying 'devil's staircase' by recording the beam velocity distribution function at the outlet of a traveling wave tube versus the amplitude of two externally induced waves.

Area as a devil's staircase in twist maps

In area-preserving maps, the area under an invariant set as a function of frequency is a devil's staircase. We show this staircase is the derivative of the average action of the invariant set with respect to frequency. This implies that resonances fill the phase space completely when there are no invariant curves.

On a Devil’s staircase associated to the joint spectral radii of a family of pairs of matrices  

E-Print Network (OSTI)

The joint spectral radius of a finite set of real d×d matrices is defined to be the maximum possible exponential rate of growth of products of matrices drawn from that set. In previous work with K. G. Hare and J. Theys we showed that for a certain one-parameter family of pairs of matrices, this maximum possible rate of growth is attained along Sturmian sequences with a certain characteristic ratio which depends continuously upon the parameter. In this note we answer some open questions from that paper by showing that the dependence of the ratio function upon the parameter takes the form of a Devil’s staircase. We show in particular that this Devil’s staircase attains every rational value strictly between 0 and 1 on some interval, and attains irrational values only in a set of Hausdorff dimension zero. This result generalises to include certain one-parameter families considered by other authors. We also give explicit formulas for the preimages of both rational and irrational numbers under the ratio function, thereby establishing a large family of pairs of matrices for which the joint spectral radius may be calculated exactly.

Exact Solution of Frenkel-Kontorova Models with a Complete Devil’s Staircase in Higher Dimensions  

E-Print Network (OSTI)

We solve exactly a class of Frenkel-Kontorova models with piecewise parabolic potential, which has d sub-wells in a period. With careful analysis, we show that the phase diagram of the minimum enthalpy configurations exhibits the structure of a complete d-dimensional devil’s staircase. The winding number of a minimum enthalpy configuration is locked to rational values, while the fraction of atoms in each sub-well is locked to values which are subcommensurable with the winding number. PACS number(s):03.20.+i, 05.45.+b, 64.60.Ak Typeset using REVTEX 1 Periodic modulated structures are quite common in both condensed-matter and dynamical systems. As suitable parameters are varied, such structures may go through commensurate-incommensurate phase transitions. In particular, when a system is in the highly nonlinear regime, there is generally a tendency for the periodicity to lock into values which are commensurable with the lattice constant [1]. The Frenkel-Kontorova (FK) model is just such an example, which describes a one-dimensional chain of coupled atoms subject to a periodic potential V: H({un}) = ?

Devil's staircase and order without periodicity in classical condensed matter  

SciTech Connect

The existence of incommensurate structures proves that crystal ordering is not always the most stable one for nonquantum matter. Some properties of structures which are obtained by minimizing a free energy are investigated in the Frenkel Kontorova and related models. It is shown that an incommensurate structure can be either quasi-sinusoidal with a phason mode or built out of a sequence of equidistant defects (discommensurations) which are locked to the lattice by the Peierls force. In that situation the variation of the commensurability ratio with physical parameters forms a complete devil's staircase with interesting physical consequences. Some general results for all structures which minimize a free energy are given. In addition to the known crystal and incommensurate structures, the existence of a new class of structures which have local order at all scale is predicted. Properties of the new class are described in physical terms and possible applications to certain amorphous or nonstoichiometric compounds are discussed.

Parallel Chip-Firing on the Complete Graph: Devil's Staircase and Poincare Rotation Number  

E-Print Network (OSTI)

We study how parallel chip-firing on the complete graph K_n changes behavior as we vary the total number of chips. Surprisingly, the activity of the system, defined as the average number of firings per time step, does not increase smoothly in the number of chips; instead it remains constant over long intervals, punctuated by sudden jumps. In the large n limit we find a "devil's staircase" dependence of activity on the number of chips. The proof proceeds by reducing the chip-firing dynamics to iteration of a self-map of the circle S^1, in such a way that the activity of the chip-firing state equals the Poincare rotation number of the circle map. The stairs of the devil's staircase correspond to periodic chip-firing states of small period.

The dimension of the set complementary to the stairs is determined to be 0.89. This demonstrates that the external-cavity semiconductor laser exhibits the universal properties characteristic for nonlinear systems driven by two competing frequencies.

Evidence for a devil's staircase in holmium produced by an applied magnetic field  

SciTech Connect

The magnetic structure of holmium has been studied using neutron diffraction when a magnetic field is applied along the {ital c} axis. The field has the effect of suppressing the onset of the commensurate cone phase found at low temperatures in zero field, and instead produces a series of spin-slip structures. In contrast to the zero-field diffraction experiments, where a continuous variation of the magnetic wave vector {bold q} was observed, we find that below {approx}15 K the wave vector {bold q} is always commensurate and forms a devil's staircase with increasing field.

Devil's staircase, spontaneous-DC bias, and chaos via quasiperiodic plasma oscillations in semiconductor superlattices  

E-Print Network (OSTI)

We study a plasma instability in semiconductor superlattices irradiated by a monochromatic, pure AC electric field. The instability leads to sustained oscillations at a frequency \\omega 2 that is either incommensurate to the drive, or frequency-locked to it, \\omega 2 = (p/q) \\omega. A spontaneously generated DC bias is found when either p or q in the locking ratio are even integers. Frequency locked regions form Arnol'd tongues in parameter space and the ratio \\omega 2 / \\omega\\ exhibits a Devil's staircase. A transition to chaotic motion is observed as resonances overlap.

Direct observation of a "devil's staircase'' in wave-particle interaction  

E-Print Network (OSTI)

We report the experimental observation of a "devil's staircase'' in a time dependent system considered as a paradigm for the transition to large scale chaos in the universality class of hamiltonian systems. A test electron beam is used to observe its non-self-consistent interaction with externally excited wave(s) in a Travelling Wave Tube (TWT). A trochoidal energy analyzer records the beam energy distribution at the output of the interaction line. An arbitrary waveform generator is used to launch a prescribed spectrum of waves along the slow wave structure (a 4 m long helix) of the TWT. The resonant velocity domain associated to a single wave is observed, as well as the transition to large scale chaos when the resonant domains of two waves and their secondary resonances overlap. This transition exhibits a "devil's staircase'' behavior for increasing excitation amplitude, due to the nonlinear forcing by the second wave on the pendulum-like motion of a charged particle in one electrostatic wave.

Josephson junction at the onset of chaos: A complete devil's staircase  

SciTech Connect

By analog computer calculations of the resistively and capacitively shunted Josephson junction model, I-V characteristics are measured for several choices of the parameters in the Josephson equation. The points, where hysteresis sets in, are related to cubic inflection points in the return map. For different values of the amplitude and the frequency of the imposed ac field the critical line is determined in the (I,G) space, where I is the dc current and G is the damping factor. Furthermore, the subharmonic steps along the critical line form a complete devil's staircase with a fractal dimension Dapprox.0.87 and a decay exponent for the (1/Q)-steps deltaapprox.3. Besides the hysteresis which gives occasion for a chaotic behavior everywhere below a certain critical voltage, hysteresis also turns up locally. It is suggested that the critical points where local hysteresis occurs can be found by use of a local approximation.

Analog simulations of josephson junction in a microwave field. Devil's staircase, fractal dimension, and decay constants  

SciTech Connect

The RSJ model of the Josephson junction in the presence of a microwave field is studied using an analog computer, with special attention to the behavior of this system near or at the critical line, where the set of substeps forms a complete devil's staircase on the I-V characteristic. A value of fractal dimension D = 0.868 +/- 0.002 is determined from 240 substeps between the winding numbers W = 0 and W = 1. Four values of decay constants are determined. The results agree very well with the prediction obtained from the one-dimensional circle map. A self-similarity graph is shown confirming that the staircase is very near the critical line. Results confirm the universal and global character of D and decay constants on the critical line, as was suggested by Jensen et al.

Twist map, the extended Frenkel-Kontorova model and the devil's staircase  

SciTech Connect

Exact results obtained on the discrete Frenkel Kontorova (FK) model and its extensions during the past few years are reviewed. These models are associated with area preserving twist maps of the cylinder (or a part of it) onto itself. The theorems obtained for the FK model thus yields new theorems for the twist maps. The exact structure of the ground-states which are either commensurate or incommensurate and assert the existence of elementary discommensurations under certain necessary and sufficient conditions is described. Necessary conditions for the trajectories to represent metastable configurations, which can be chaotic, are given. The existence of a finite Peierl Nabarro barrier for elementary discommensurations is connected with a property of non-integrability of the twist map. The existence of KAM tori corresponds to undefectible incommensurate ground-states and a theorem is given which asserts that when the phenon spectrum of an incommensurate ground-state exhibits a finite gap, then the corresponding trajectory is dense on a Cantor set with zero measure length. These theorems, when applied to the initial FK model, allows one to prove the existence of the transition by breaking of analyticity for the incommensurate structures when the parameter which describes the discrepancy of the model to the integrable limit varies. Finally, we describe a theorem proving the existence of a devil's staircase for the variation curve of the atomic mean distance versus a chemical potential, for certain properties of the twist map which are generally satisfied.

On the amplitude of External Perturbation and the Chaos via Devil's Staircase and the Hidden Attractors

We made the chaotic circuit proposed by Chua and the memristic circuit proposed by Muthuswamy and Chua, and analyzed the behavior of the voltage of the capacitor, electric current in the inductor and the voltage of the memristor by adding an external sinusoidal oscillation ${\\dot y}(t)\\simeq {\\dot i_L}(t)$ of a type $\\gamma\\omega \\cos\\omega t$, while the ${\\dot x}(t)\\simeq {\\dot v_C}(t)$ is given by $y(t)/C$, and studied the Devil's staircase route to chaos. We compared the frequency of the driving oscillation $f_s$ and the frequency of the response $f_d$ in the window and assigned $W=f_s/f_d$ to each window. When capacitor $C=1$, we observe stable attractors of Farey sequences $\\displaystyle W=\\{\\frac{1}{2}, \\frac{2}{3},\\frac{3}{4},\\frac{4}{5}, \\cdots ,\\frac{14}{15},\\frac{1}{1}\\}$, which can be interpreted as hidden attractors, while when $C=1.2$, we observe unstable attractors. Possible role of octonions in quantum mechanics and Cartan's supersymmetry is discussed.

On a Devil's staircase associated to the joint spectral radii of a family of pairs of matrices  

E-Print Network (OSTI)

The joint spectral radius of a finite set of real d x d matrices is defined to be the maximum possible exponential rate of growth of products of matrices drawn from that set. In previous work with K. G. Hare and J. Theys we showed that for a certain one-parameter family of pairs of matrices, this maximum possible rate of growth is attained along Sturmian sequences with a certain characteristic ratio which depends continuously upon the parameter. In this note we answer some open questions from that paper by showing that the dependence of the ratio function upon the parameter takes the form of a Devil's staircase. We show in particular that this Devil's staircase attains every rational value strictly between 0 and 1 on some interval, and attains irrational values only in a set of Hausdorff dimension zero. This result generalises to include certain one-parameter families considered by other authors. We also give explicit formulas for the preimages of both rational and irrational numbers under the ratio function,...

'Devil's Staircase'-Type Phase Transition in NaV{sub 2}O{sub 5} under High Pressure  

SciTech Connect

The 'devil's staircase'-type phase transition in the quarter-filled spin-ladder compound NaV{sub 2}O {sub 5} has been discovered at low temperature and high pressure by synchrotron radiation x-ray diffraction. A large number of transitions are found to successively take place among higher-order commensurate phases with 2a x 2b x zc type superstructures. The observed temperature and pressure dependence of modulation wave number q{sub c}, defined by 1/z, is well reproduced by the axial next nearest neighbor Ising model. The q{sub c} is suggested to reflect atomic displacements presumably coupled with charge ordering in this system.

Growing smooth interfaces with inhomogeneous, moving external fields: dynamical transitions, devil's staircases and self-assembled ripples  

E-Print Network (OSTI)

We study the steady state structure and dynamics of an interface in a pure Ising system on a square lattice placed in an inhomogeneous external field. The field has a profile with a fixed shape designed to stabilize a flat interface, and is translated with velocity v_e. For small v_e, the interface is stuck to the profile, is macroscopically smooth, and is rippled with a periodicity in general incommensurate with the lattice parameter. For arbitrary orientations of the profile, the local slope of the interface locks in to one of infinitely many rational values (devil's staircase) which most closely approximates the profile. These ``lock-in'' structures and ripples dissappear as v_e increases. For still larger v_e the profile detaches from the interface which is now characterized by standard Kardar-Parisi-Zhang (KPZ) exponents.

A formula for the fractal dimension d approx. 0.87 of the Cantorian set underlying the Devil's staircase associated with the Circle Map  

E-Print Network (OSTI)

The Cantor set complementary to the Devil's Staircase associated with the Circle Map has a fractal dimension d approximately equal to 0.87, a value that is universal for a wide range of maps, such results being of a numerical character. In this paper we deduce a formula for such dimensional value. The Devil's Staircase associated with the Circle Map is a function that transforms horizontal unit interval I onto vertical I, and is endowed with the Farey-Brocot (F-B) structure in the vertical axis via the rational heights of stability intervals. The underlying Cantor-dust fractal set Omega in the horizontal axis --Omega contained in I, with fractal dimension d(Omega) approx. 0.87-- has a natural covering with segments that also follow the F-B hierarchy: therefore, the staircase associates vertical I (of unit dimension) with horizontal Omega in I (of dimension approx. 0.87), i.e. it selects a certain subset Omega of I, both sets F- B structured, the selected Omega with smaller dimension than that of I. Hence, the...

Strain versus stress in a model granular material: a Devil's staircase  

E-Print Network (OSTI)

The series of equilibrium states reached by disordered packings of rigid, frictionless discs in two dimensions, under gradually varying stress, are studied by numerical simulations. Statistical properties of trajectories in configuration space are found to be independent of specific assumptions ruling granular dynamics, and determined by geometry only. A monotonic increase in some macroscopic loading parameter causes a discrete sequence of rearrangements. For a biaxial compression, we show that, due to the statistical importance of such events of large magnitudes, the dependence of the resulting strain on stress direction is a Levy flight in the thermodynamic limit.

NOVEL NANOCOMPOSITE MEMBRANE STRUCTURES FOR H2 SEPARATIONS  

SciTech Connect

This report explores possible methods of improving CO{sub 2} selectivity in polymer based membranes. The first method investigated using basic nanoparticles to enhance the solubility of acid gases in nanocomposite membranes, thus enhancing the overall acid gas/light gas selectivity (e.g., CO{sub 2}/H{sub 2}, CO{sub 2}/CH{sub 4}, etc.). The influence of nanoparticle surface chemistry on nanocomposite morphology and transport properties will be determined experimentally in a series of poly(1-trimethylsilyl-1-propyne). Additional factors (e.g., chemical reaction of the particles with the polymers) have been considered, as necessary, during the course of the investigation. The second method investigated using polar polymers such as crosslinked poly(ethylene oxide) and poly(ether-b-amide) to improve CO{sub 2} sorption and thereby increase CO{sub 2} permeability and CO{sub 2}/light gas selectivity. For both types of materials, CO{sub 2} and light gas permeabilities have been characterized. The overall objective was to improve the understanding of materials design strategies to improve acid gas transport properties of membranes.

SUBTASK 7.2 GLOBAL WARMING AND GREEHOUSE GASES  

SciTech Connect

Evaluation of current climatic trends and reconstruction of paleoclimatic conditions for Devils Lake have been conducted based on diatom-inferred salinity for the last 2000 years. The 3-year cross-disciplinary research, funded by the U.S. Department of Energy (DOE) was carried out by the Energy & Environmental Research Center (EERC) and St. Croix Watershed Research Station (SCWRS) at the Science Museum of Minnesota. The results indicate that frequent climatic fluctuations resulting in alternating periods of drought and wet conditions are typical for the northern Great Plains and suggest that the severity and length of extremes exceeded those on modern record. Devils Lake has experienced five fresh periods and two minor freshening periods in the last 2000 years. Transitions between fresh and saline periods have been relatively fast, representing lake level changes that have been similar to those observed in the last 150 years. From 0 to 1070 A.D., Devils Lake showed more variable behavior, with fresh phases centered at 200, 500, 700, and 1000 A.D. From 1070 A.D. to present, Devils Lake was generally saline, experiencing two minor freshening periods at 1305-1315 and 1800-1820 A.D and the major current freshening from 1960 A.D. to present.

Renormalization, unstable manifolds, and the fractal structure of mode locking  

SciTech Connect

The apparent universality of the fractal dimension of the set of quasiperiodic windings at the onset of chaos in a wide class of circle maps is described by construction of a universal one-parameter family of maps which lies along the unstable manifold of the renormalization group. The manifold generates a universal ''devil's staircase'' whose dimension agrees with direct numerical calculations. Applications to experiments are discussed.

Studies of chaos and thermal noise in a driven Josephson junction using an electronic analog  

SciTech Connect

Using an electronic analog of a resistively shunted driven Josephson junction, the authors have demonstrated a number of effects, including the appearance of a devil's staircase in the current-voltage characteristic, the onset of chaos, and the effect of noise on these phenomena. The authors stress that the analog is simple, but models the junction behavior with a high degree of accuracy and detail.

Successive Phase Transitions in Antiferroelectric Liquid Crystal Systems  

E-Print Network (OSTI)

An axial next-nearest-neighbor XY model is studied as a model of chiral liquid crystals which exhibit many ferro-, ferri- and antiferroelectric tilted smectic phases. Depending on the values of interaction parameters, this model exhibits Ising symmetric (i.e., the tilt directions of directors are parallel or anti parallel) phases or XY symmetric phases. Phases with each type-of-symmetry show the character of devil's staircase, which has been observed in experiments.

One-dimensional Ising model in a random field  

SciTech Connect

The one-dimensional Ising model in a random field is studied with use of a functional recursion relation. For temperatures exceeding a given value, the fixed function of the relation is found and shown to be a devil's staircase. From this result it is possible to evaluate the free energy to arbitrary precision. In the field-strength--temperature plane, a crossover line corresponding to the onset of frustration is found.

Evaluation of Background Concentrations of Contaminants in an Unusual Desert Arroyo Near a Uranium Mill Tailings Disposal Cell - 12260  

SciTech Connect

The U.S. Department of Energy (DOE) Office of Legacy Management (LM) manages 27 sites that have groundwater containing uranium concentrations above background levels. The distal portions of the plumes merge into background groundwater that can have 50 ?g/L or more uranium. Distinguishing background from site-related uranium is often problematic, but it is critical to determining if remediation is warranted, establishing appropriate remediation goals, and evaluating disposal cell performance. In particular, groundwater at disposal cells located on the upper Cretaceous Mancos Shale may have relatively high background concentrations of uranium. Elevated concentrations of nitrate, selenium, and sulfate accompany the uranium. LM used geologic analogs and uranium isotopic signatures to distinguish background groundwater from groundwater contaminated by a former uranium processing site. The same suite of contaminants is present in groundwater near former uranium processing sites and in groundwater seeps emanating from the Mancos Shale over a broad area. The concentrations of these contaminants in Many Devils Wash, located near LM's Shiprock disposal cell, are similar to those in samples collected from many Mancos seeps, including two analog sites that are 8 to 11 km from the disposal cell. Samples collected from Many Devils Wash and the analog sites have high AR values (about 2.0)-in contrast, groundwater samples collected near the tailings disposal cell have AR values near 1.0. These chemical signatures raise questions about the origin of the contamination seeping into Many Devils Wash. (authors)

The staircase structure of the Southern Brazilian Continental Shelf  

E-Print Network (OSTI)

We show some evidences that the Southeastern Brazilian Continental Shelf (SBCS) has a devil's staircase structure, with a sequence of scarps and terraces with widths that obey fractal formation rules. Since the formation of these features are linked with the sea level variations, we say that the sea level changes in an organized pulsating way. Although the proposed approach was applied in a particular region of the Earth, it is suitable to be applied in an integrated way to other Shelves around the world, since the analyzes favor the revelation of the global sea level variations.

Quantum Catalysis of Magnetic Phase Transitions in a Quantum Simulator  

E-Print Network (OSTI)

We control quantum fluctuations to create the ground state magnetic phases of a classical Ising model with a tunable longitudinal magnetic field using a system of 6 to 10 atomic ion spins. Due to the long-range Ising interactions, the various ground state spin configurations are separated by multiple first-order phase transitions, which in our zero temperature system cannot be driven by thermal fluctuations. We instead use a transverse magnetic field as a quantum catalyst to observe the first steps of the complete fractal devil's staircase, which emerges in the thermodynamic limit and can be mapped to a large number of many-body and energy-optimization problems.

Mode locking and chaos in sliding charge-density-wave systems  

SciTech Connect

Sliding CDWs in ac electric fields may serve as model systems for the study of mode-locking phenomena and the transition to chaos in dissipative dynamical system with competing frequencies. The mode-locking structure at the transition is expected to form a complete devil's staircase with fractal dimension D approx. 0.87. Indeed, Brown, Mozurkewich and Gruener have observed a multitude of steps in the I-V characteristics of NbSe/sub 3/ with an apparent fractal dimension D = 0.91 +- 0.03. 16 references.

Two-dimensional random walk in a bounded domain

In a recent Letter Ciftci and Cakmak [EPL 87, 60003 (2009)] showed that the two dimensional random walk in a bounded domain, where walkers which cross the boundary return to a base curve near origin with deterministic rules, can produce regular patterns. Our numerical calculations suggest that the cumulative probability distribution function of the returning walkers along the base curve is a Devil's staircase, which can be explained from the mapping of these walks to a non-linear stochastic map. The non-trivial probability distribution function(PDF) is a universal feature of CCRW characterized by the fractal dimension d=1.75(0) of the PDF bounding curve.

Stochastic modeling of Congress  

E-Print Network (OSTI)

We analyze the dynamics of growth of the number of congressmen supporting the resolution HR1207 to audit the Federal Reserve. The plot of the total number of co-sponsors as a function of time is of "Devil's staircase" type. The distribution of the numbers of new co-sponsors joining during a particular day (step height) follows a power law. The distribution of the length of intervals between additions of new co-sponsors (step length) also follows a power law. We use a modification of Bak-Tang-Wiesenfeld sandpile model to simulate the dynamics of Congress and obtain a good agreement with the data.

Arnold tongues for a resonant injection-locked frequency divider: analytical and numerical results  

E-Print Network (OSTI)

In this paper we consider a resonant injection-locked frequency divider which is of interest in electronics, and we investigate the frequency locking phenomenon when varying the amplitude and frequency of the injected signal. We study both analytically and numerically the structure of the Arnold tongues in the frequency-amplitude plane. In particular, we provide exact analytical formulae for the widths of the tongues, which correspond to the plateaux of the devil's staircase picture. The results account for numerical and experimental findings presented in the literature for special driving terms and, additionally, extend the analysis to a more general setting.

Simultaneous ordering of holes and spins in La[sub 2]NiO[sub 4. 125  

SciTech Connect

We report a single-crystal neutron diffraction study of the incommensurate magnetic ordering that occurs in La[sub 2]NiO[sub 4.125] below 110 K. Besides the magnetic first and third harmonic Bragg peaks, we have also observed second harmonic peaks associated with charge ordering. The magnitude of the incommensurate splitting, [epsilon], is strongly temperature dependent. Lock-in behavior indicates that [epsilon] tends to rational fractions, while regions of continuous variation suggest a devil's staircase. Analysis of these features indicates that the holes, induced by the excess oxygen, order in domain walls that form antiphase boundaries between antiferromagnetic domains.

Quantum Phases of Cold Polar Molecules in 2D Optical Lattices

We study the quantum phases of hard-core bosonic polar molecules on a two-dimensional square lattice interacting via repulsive dipole-dipole interactions. In the limit of small tunneling, we find evidence for a devil's staircase, where Mott solids appear at rational fillings of the lattice. For finite tunneling, we establish the existence of extended regions of parameters where the ground state is a supersolid, obtained by doping the solids either with particles or vacancies. We discuss the effects of finite temperature and finite-size confining potentials as relevant to experiments.

Anderson localization for one-dimensional difference Schroedinger operator with quasiperiodic potential  

SciTech Connect

The Schroedinger difference operator considered here has the form (H/sub epsilon/(..cap alpha..)psi)(n) = -epsilon(psi(n + 1) + psi(n - 1)) + V(nomega + ..cap alpha..psi(n) where V is a C/sup 2/-periodic Morse function taking each value at not more than two points. It is shown that for sufficiently small epsilon the operator H/sub epsilon/(..cap alpha..) has for a.e. ..cap alpha.. a pure point spectrum. The corresponding eigenfunctions decay exponentially outside a finite set. The integrated density of states is an incomplete devil's staircase with infinitely many flat pieces.

Two-stage melting of solids in strongly interacting Rydberg atoms  

E-Print Network (OSTI)

We analyze the ground state properties of a one-dimensional cold atomic system in a lattice, where Rydberg excitations are created by an external laser drive. In the classical limit, the ground state is characterized by a complete devil's staircase for the commensurate solid structures of Rydberg excitations. Using perturbation theory and a mapping onto an effective low energy Hamiltonian, we find a transition of these commensurate solids into a floating solid with algebraic correlations. For stronger quantum fluctuations the floating solid eventually melts within a second quantum phase transition and the ground state becomes paramagnetic.

Study of an Ising model with competing long- and short-range interactions  

SciTech Connect

A classical spin-one lattice gas model is used to study the competition between short-range ferromagnetic coupling and long-range antiferromagnetic Coulomb interactions. The model is a coarse-grained representation of frustrated phase separation in high-temperature superconductors. The ground states are determined for the complete range of parameters by using a combination of numerical and analytical techniques. The crossover between ferromagnetic and antiferromagnetic states proceeds via a rich structure of highly symmetric striped and checkerboard phases.

Two-Stage Melting in Systems of Strongly Interacting Rydberg Atoms  

SciTech Connect

We analyze the ground state properties of a one-dimensional cold atomic system in a lattice, where Rydberg excitations are created by an external laser drive. In the classical limit, the ground state is characterized by a complete devil's staircase for the commensurate solid structures of Rydberg excitations. Using perturbation theory and a mapping onto an effective low-energy Hamiltonian, we find a transition of these commensurate solids into a floating solid with algebraic correlations. For stronger quantum fluctuations the floating solid eventually melts within a second quantum phase transition and the ground state becomes paramagnetic.

Twelve Months of Air Quality Monitoring at Ash Meadows National Wildlife Refuge, Southwestern Rural Nevada, U.S.A (EMSI April 2007)  

SciTech Connect

The one year of air quality monitoring data collected at the Ash Meadows National Wildlife Refuge (NWR) was the final part of the air quality "Scoping Studies" for the Environmental Monitoring Systems Initiative (EMSI) in southern and central Nevada. The objective of monitoring at Ash Meadows was to examine aerosol and meteorological data, seasonal trends in aerosol and meteorological parameters as well as to examine evidence for long distance transport of some constituents. The 9,307 hectare refuge supports more than 50 springs and 24 endemic species, including the only population of the federally listed endangered Devil’s Hole pupfish (Cyprinodon diabolis) (U.S. Fish and Wildlife Service, 1990). Ash Meadows NWR is located in a Class II air quality area, and the aerosol measurements collected with this study are compared to those of Interagency Monitoring of Protected Visual Environments (IMPROVE) sites. Measurements taken at Ash Meadows NWR over a period of 12 months provide new baseline air quality and meteorological information for rural southwestern Nevada, specifically Nye County and the Amargosa Valley.

Field studies of the potential for wind transport of plutonium- contaminated soils at sites in Areas 6 and 11, Nevada Test Site  

SciTech Connect

This report describes and documents a series of field experiments carried out in Areas 6 and 11 of the Nevada Test Site in June and July 1994 to determine parameters of boundary layer winds, surface characteristics, and vegetation cover that can be used to predict dust emissions from the affected sites. Aerodynamic roughness of natural sites is determined largely by the lateral cover of the larger and more permanent roughness elements (shrubs). These provide a complete protection of the surface from wind erosion. Studies using a field-portable wind tunnel demonstrated that natural surfaces in the investigated areas of the Nevada Test Site are stable except at very high wind speeds (probably higher than normally occur, except perhaps in dust devils). However, disturbance of silty-clay surfaces by excavation devices and vehicles reduces the entrainment threshold by approximately 50% and makes these areas potentially very susceptible to wind erosion and transport of sediments.

Modulated order in classical magnetoelastic chains  

SciTech Connect

We investigate the nature of modulated lattice distortions that can occur in a two-dimensional array of classical magnetoelastic chains coupled together by elastic interactions only. The phase diagram for the lattice structure is obtained by numerically minimizing a one-dimensional, temperature-dependent, effective-free-energy functional of the elastic variables. At zero temperature, only phases where the winding number is uniquely defined are found, and the transitions among these phases are suggestive of a complete devil's-staircase behavior. These numerical results are consistent with N. Ishimura's analytic demonstration that such a staircase exists (J. Phys. Soc. Jpn. 54, 4752 (1985)). At finite temperatures, phases where the winding number is not uniquely defined are found and, in addition, first- and second-order transitions appear. Also of interest are superdegenerate lines where the equilibrium phase is composed of noninteracting solitons of zero energy.

Neutral-ionic transitions in organic mixed-stack compounds  

SciTech Connect

Torrance et al. have made the interesting observation that several mixed-stack organic compounds undergo transitions from neutral states to ionic states as the temperature or pressure is varied. We examine a simple model of such transitions including Coulomb interaction and hybridization of neutral and ionic states. In the limit of weak hybridization and long-range repulsive interaction between ionic planes, it is proven that there is a complete devil's staircase where the degree of ionicity assumes an infinity of rational values. For attractive interactions between ionic planes, the neutral-ionic transition is shown to be first order for weak hybridization. Comparison with experiment indicates that this situation applies to tetrathiafulvalene (TTF) chloranil. For strong hybridization the transition is continuous but goes through a metallic phase. It is shown, for the first time, that the spectrum of the charge-transfer Hamiltonian contains both a bound spectrum, the observed charge-transfer excitations, and a continuum.

Pinning and annealing of solitons in modulated systems  

SciTech Connect

Chaotic pinning of solitons occurs in nearly commensurate modulated systems when the distance between solitons becomes so large that their interaction cannot overcome the Peierls pinning potential. We study numerically within the mean-field theory the stability of the randomly pinned ''chaotic'' states as a function of temperature near the commensurate-incommensurate (CI) transition in the axial next-nearest-neighbor Ising model. The pinned state turns into a regular incommensurate state as the temperature is raised. A more regular soliton state emerges as the temperature is lowered. The system never reaches the ground state (Frank and van der Merwe or devil's-staircase behavior) near the CI transition because of the pinning. The chaos and the hysteresis may explain recent experimental findings in magnetic and ferroelectric systems.

Stochastic modeling of a serial killer  

E-Print Network (OSTI)

We analyze the time pattern of the activity of a serial killer, who during twelve years had murdered 53 people. The plot of the cumulative number of murders as a function of time is of "Devil's staircase" type. The distribution of the intervals between murders (step length) follows a power law with the exponent of 1.4. We propose a model according to which the serial killer commits murders when neuronal excitation in his brain exceeds certain threshold. We model this neural activity as a branching process, which in turn is approximated by a random walk. As the distribution of the random walk return times is a power law with the exponent 1.5, the distribution of the inter-murder intervals is thus explained. We confirm analytical results by numerical simulation.

Photon Long-Range Repulsive Interaction in the Jaynes-Cummings Lattice with Rydberg Atoms  

E-Print Network (OSTI)

We propose how to realize a strong photon long-range repulsive interaction by controlling the van der Waals repulsive force between Rydberg atoms located in different cavities in extended Jaynes-Cumings-Hubbard lattices. We find that this photon long-range repulsive interaction can generate complex quantum phases, some of which have no analogy in condensed-matter and atomic physics. For example, without photon hopping, a photon devil's staircase induced by the breaking of long-range translation symmetry can emerge. If photon hopping occurs, we predict a photon-floating solid phase, due to the motion of particle- and hole-like defects. More importantly, for a large chemical potential in the resonant case, the photon hopping can detected by measuring the number of polaritons via resonance fluorescence.

Behavior of the Escape Rate Function in Hyperbolic Dynamical Systems  

E-Print Network (OSTI)

For a fixed initial reference measure, we study the dependence of the escape rate on the hole for a smooth or piecewise smooth hyperbolic map. First, we prove the existence and Holder continuity of the escape rate for systems with small holes admitting Young towers. Then we consider general holes for Anosov diffeomorphisms, without size or Markovian restrictions. We prove bounds on the upper and lower escape rates using the notion of pressure on the survivor set and show that a variational principle holds under generic conditions. However, we also show that the escape rate function forms a devil's staircase with jumps along sequences of regular holes and present examples to elucidate some of the difficulties involved in formulating a general theory.

Structural constraints for proposed Fort Hancock low-level radioactive waste disposal site (NTP-S34), southern Hudspeth County, Texas  

SciTech Connect

Structural complexities reduce the homogeneity necessary for a site characterization model to an unacceptable level for performance assessment for radioactive waste disposal sites. The proposed site lies between the northern, stable Diablo platform and the southern, mobile Mesozoic Chihuahua tectonic belt. Structural movement along this interface has been active for the past 14,000 years. In addition, the area lies along the northern margin of the Permian Marfa basin and the northeastern margin of the deeply faulted Hueco bolson segment of the late Cenozoic Rio Grande rift system. Recent seismic activity with extensive surface rupture in Quitman Canyon (30 mi southeast of the site) is also documented from the 1931 Valentine, Texas, earthquake (6.4 Richter scale). The site is underlain by either a thrust fault or the complex terminus of a Mesozoic thrust fault. This fault is a segment of the continuous thrust sheet extending from exposures in the Sierra Blanc area, 30 mi east (Devil Ridge fault), to the El Paso area west (Rio Grande fault). This segment of the Devil Ridge-Rio Grande thrust is documented by the Haymond Krupp No. 1 Thaxton wildcat drilled at Campogrande Mountain immediately south of the site. The recent rift fault scarp (Campo Grande) immediately south of the Thaxton well has a 17-mi surface trace and is, no doubt, related to the subsurface Clint fault to the west in the El Paso area. An additional complexity is the presence of a monoclinal flexure with a minimum of 900 ft of surface relief (2 mi northeast of NTP-S34). A 4.5-mi, east-west, down-to-the-south normal fault occurs near the top of the monocline with a small associated graben. These complexities seriously compromise the proposed Fort Hancock site.

Parallel heat transport in integrable and chaotic magnetic fields  

SciTech Connect

The study of transport in magnetized plasmas is a problem of fundamental interest in controlled fusion, space plasmas, and astrophysics research. Three issues make this problem particularly challenging: (i) The extreme anisotropy between the parallel (i.e., along the magnetic field), {chi}{sub ||} , and the perpendicular, {chi}{sub Up-Tack }, conductivities ({chi}{sub ||} /{chi}{sub Up-Tack} may exceed 10{sup 10} in fusion plasmas); (ii) Nonlocal parallel transport in the limit of small collisionality; and (iii) Magnetic field lines chaos which in general complicates (and may preclude) the construction of magnetic field line coordinates. Motivated by these issues, we present a Lagrangian Green's function method to solve the local and non-local parallel transport equation applicable to integrable and chaotic magnetic fields in arbitrary geometry. The method avoids by construction the numerical pollution issues of grid-based algorithms. The potential of the approach is demonstrated with nontrivial applications to integrable (magnetic island), weakly chaotic (Devil's staircase), and fully chaotic magnetic field configurations. For the latter, numerical solutions of the parallel heat transport equation show that the effective radial transport, with local and non-local parallel closures, is non-diffusive, thus casting doubts on the applicability of quasilinear diffusion descriptions. General conditions for the existence of non-diffusive, multivalued flux-gradient relations in the temperature evolution are derived.

Chaos Pass Filter: Linear Response of Synchronized Chaotic Systems  

E-Print Network (OSTI)

The linear response of synchronized time-delayed chaotic systems to small external perturbations, i.e., the phenomenon of chaos pass filter, is investigated for iterated maps. The distribution of distances, i.e., the deviations between two synchronized chaotic units due to external perturbations on the transfered signal, is used as a measure of the linear response. It is calculated numerically and, for some special cases, analytically. Depending on the model parameters this distribution has power law tails in the region of synchronization leading to diverging moments of distances. This is a consequence of multiplicative and additive noise in the corresponding linear equations due to chaos and external perturbations. The linear response can also be quantified by the bit error rate of a transmitted binary message which perturbs the synchronized system. The bit error rate is given by an integral over the distribution of distances and is calculated analytically and numerically. It displays a complex nonmonotonic behavior in the region of synchronization. For special cases the distribution of distances has a fractal structure leading to a devil's staircase for the bit error rate as a function of coupling strength. The response to small harmonic perturbations shows resonances related to coupling and feedback delay times. A bi-directionally coupled chain of three units can completely filtered out the perturbation. Thus the second moment and the bit error rate become zero.

Data-Adaptive Wavelets and Multi-Scale Singular Spectrum Analysis  

E-Print Network (OSTI)

Using multi-scale ideas from wavelet analysis, we extend singular-spectrum analysis (SSA) to the study of nonstationary time series of length $N$ whose intermittency can give rise to the divergence of their variance. SSA relies on the construction of the lag-covariance matrix C on M lagged copies of the time series over a fixed window width W to detect the regular part of the variability in that window in terms of the minimal number of oscillatory components; here W = M Dt, with Dt the time step. The proposed multi-scale SSA is a local SSA analysis within a moving window of width M fractal or power-law behavior which mimic selected features of certain climatic and geophysical time series. A real application is to the Southern Oscillation index (SOI) monthly values for 1933-1996. Our methodology highlights an abrupt periodicity shift in the SOI near 1960. This abrupt shift between 4 and 3 years supports the Devil's staircase scenario for the El Nino/Southern Oscillation phenomenon.

We have investigated the transition through a study of discrete maps of the circle onto itself, and by constructing and analyzing return maps of differential equations representing some physical systems. The transition is caused by interaction and overlap of mode-locked resonances and takes place at a critical line where the map losses invertibility. At this line the mode-locked intervals trace up a complete Devil's Staircase whose complementary set is a Cantor set with universal fractal dimension D approx. 0.87. Below criticality there is room for quasiperiodic orbits, whose measure is given by an exponent ..beta.. approx. 0.34 which can be related to D through a scaling relation, just as for second order phase transitions. The Lebesgue measure serves as an order parameter for the transition to chaos. The resistively shunted Josephson junction, and charge density waves (CDWs) in rf electric fields are usually described by the differential equation of the damped driven pendulum. The 2d return map for this equation collapses to ld circle map at and below the transition to chaos. The theoretical results on universal behavior, derived here and elsewhere, can thus readily be checked experimentally by studying real physical systems. Recent experiments on Josephson junctions and CDWs indicating the predicted fractal scaling of mode-locking at criticality are reviewed.

Transition to chaos by interaction of resonances in dissipative systems. I. Circle maps  

SciTech Connect

Dissipative dynamical systems with two competing frequencies exhibit transitions to chaos. We have investigated the transition through a study of discrete maps of the circle onto itself. The transition is caused by interaction and overlap of mode-locked resonances and occurs at a critical line where the map loses invertibility. At this line the mode-locked intervals trace up a complete devil's staircase whose complementary set is a Cantor set with fractal dimension Dapprox.0.87. Numerical results indicate that the dimension is universal for maps with cubic inflection points. Below criticality the staircase is incomplete, leaving room for quasiperiodic behavior. The Lebesgue measure of the quasiperiodic orbits seems to be given by an exponent ..beta..approx.0.35 which can be related to D through the scaling relation D = 1-..beta../..nu... The exponent ..nu.. characterizes the cutoff of narrow plateaus near the transition. A variety of other exponents describing the transition to chaos is defined and estimated numerically.

Spectra and gap amplification for systems with two widely different incommensurate periodicities  

SciTech Connect

We derive analytically the spectrum for the Schroedinger equation for quasiperiodic systems with two length scales: one large ''macroscopic'' scale (e.g., a-italic cos(2..pi..x-italic/lambda)) and one small ''microscopic'' scale (e.g., v-italic cos(2..pi..x-italic)). The phase diagram includes regimes with exponentially narrow gaps due to the slowly varying potential, regimes where the rapidly varying potential amplifies these narrow gaps, and regimes with exponentially narrow ''Landau bands.'' The full ''devil's-staircase'' spectrum with gaps at wave vectors q-italic = m-italic..pi..+n-italic..pi../lambda develops in a hierarchical manner as a-italic increases. The results apply to systems with superlattices, to celestial orbits with two periodic perturbations, to systems with slowly varying lattice distortions, and, in particular, to quasi-one-dimensional magnets such as bis(tetramethyltetraselenafulvalene) perchlorate ((TMTSF)/sub 2/ClO/sub 4/) in magnetic fields, where our findings may provide insight into the experimentally observed cascade of phase transitions.

Wave-particle interaction and Hamiltonian dynamics investigated in a traveling wave tube  

SciTech Connect

For wave-particle interaction studies, the one-dimensional (1-D) beam-plasma system can be advantageously replaced by a Traveling Wave Tube (TWT). This led us to a detailed experimental analysis of the self-consistent interaction between unstable waves and a small either cold or warm beam. More recently, a test electron beam has been used to observe its non-self-consistent interaction with externally excited wave(s). The velocity distribution function of the electron beam is investigated with a trochoidal energy analyzer that records the beam energy distribution at the output of the TWT. An arbitrary waveform generator is used to launch a prescribed spectrum of waves along the slow wave structure (a 4 m long helix) of the TWT. The nonlinear synchronization of particles by a single wave responsible for Landau damping is observed. The resonant velocity domain associated to a single wave is also observed, as well as the transition to large-scale chaos when the resonant domains of two waves and their secondary resonances overlap leading to a typical 'devil's staircase' behavior. A new strategy for the control of chaos is tested.

Dislocation-mediated melting of one-dimensional Rydberg crystals  

SciTech Connect

We consider cold Rydberg atoms in a one-dimensional optical lattice in the Mott regime with a single atom per site at zero temperature. An external laser drive with Rabi frequency {Omega} and laser detuning {Delta} creates Rydberg excitations whose dynamics is governed by an effective spin-chain model with (quasi) long-range interactions. This system possesses intrinsically a large degree of frustration resulting in a ground-state phase diagram in the ({Delta},{Omega}) plane with a rich topology. As a function of {Delta}, the Rydberg blockade effect gives rise to a series of crystalline phases commensurate with the optical lattice that form a so-called devil's staircase. The Rabi frequency {Omega}, on the other hand, creates quantum fluctuations that eventually lead to a quantum melting of the crystalline states. Upon increasing {Omega}, we find that generically a commensurate-incommensurate transition to a floating Rydberg crystal that supports gapless phonon excitations occurs first. For even larger {Omega}, dislocations within the floating Rydberg crystal start to proliferate and a second, Kosterlitz-Thouless-Nelson-Halperin-Young dislocation-mediated melting transition finally destroys the crystalline arrangement of Rydberg excitations. This latter melting transition is generic for one-dimensional Rydberg crystals and persists even in the absence of an optical lattice. The floating phase and the concomitant transitions can, in principle, be detected by Bragg scattering of light.

COMMENTS ON THE SEARCH FOR ELECTROSTATIC DISCHARGES ON MARS  

SciTech Connect

Ruf et al. used the Deep Space Network (DSN) to search for the emission of non-thermal radiation by martian dust storms, theoretically predicted by Renno et al. They detected the emission of non-thermal radiation that they were searching for, but were surprised that it contained spectral peaks suggesting modulation at various frequencies and their harmonics. Ruf et al. hypothesized that the emission of non-thermal radiation was caused by electric discharges in a deep convective dust storm, modulated by Schumann resonances (SRs). Anderson et al. used the Allen Telescope Array (ATA) to search for similar emissions. They stated that they found only radio frequency interference (RFI) during their search for non-thermal emission by martian dust storms and implicitly suggested that the signal detected by Ruf et al. was also RFI. However, their search was not conducted during the dust storm season when deep convective storms are most likely to occur. Here, we show that the ubiquitous dust devils and small-scale dust storms that were instead likely present during their observations are too shallow to excite SRs and produce the signals detected by Ruf et al. We also show that the spectral and temporal behavior of the signals detected by Anderson et al. corroborates the idea that they originated from man-made pulse-modulated telecommunication signals rather than martian electric discharges. In contrast, an identical presentation of the signals detected by Ruf et al. demonstrates that they do not resemble man-made signals. The presentation indicates that the DSN signals were consistent with modulation by martian SRs, as originally hypothesized by Ruf et al. We propose that a more comprehensive search for electrostatic discharges be conducted with either the ATA or DSN during a future martian dust storm season to test the hypothesis proposed by Ruf et al.

Radionuclide transport from yucca Mountain and Inter-basin Flow in Death Valley  

SciTech Connect

Hydrodynamics and the U.S. Geological survey conducted studies to evaluate far-field issues related to potential transport, by ground water, of radionuclide into Inyo County from Yucca Mountain, including Death Valley, and the evaluation of a connection between the Lower Carbonate Aquifer (LCA) and the biosphere. Our oversight and completed Cooperative Agreement research, and a number of other investigators research indicate that there is groundwater flow between the alluvial and carbonate aquifers both at Yucca Mountain and in Inyo County. The specific purpose of our research was to acquire geological, subsurface geology, and hydrologic data to: 1. Establish the existence of inter-basin flow between the Amargosa Basin and Death Valley Basin, 2. Characterize groundwater flow paths in the LCA through Southern Funeral Mountain Range, and 3. Evaluate the hydraulic connection between the Yucca Mountain repository and the major springs in Death Valley through the LCA. 4. Evaluate the hydraulic connection between the Yucca Mountain repository and Franklin Lake Playa. The hydraulic characterization of the LCA is of critical interest to Inyo County and the U.S. Department of Energy because: 1. The upward gradient in the LCA at Yucca Mountain provides a natural barrier to radionuclide transport, 2. The LCA is a necessary habitat resource for the endangered Devil's Hole pup fish, and 3. The LCA is the primary water supply and source of water to the major springs in Death Valley National Park. This paper presents the results of our study program to evaluate if inter-basin flow exists between the Amargosa and Death Valley Basins through the LCA. The study presents the results of our structural geology analysis of the Southern Funeral Mountain range, geochemical source analysis of spring waters in the region, and a numerical groundwater model to simulate inter-basin flow in the Southern Funeral Mountain range.

Water table controlled syndepositional alteration textures and fabrics in salt pan halite: Modern analogues and ancient examples  

SciTech Connect

At the Devil's Golf Course, Death Valley, CA, vadose zone and phreatic zone alteration of subaqueously accumulated halite produces characteristic textures and fabrics that are recognizable in ancient salt pan halite (Late Permian Salado Formation) exposed in a shaft at the Waste Isolation Pilot Plant. Water table depth and duration control fabric type. The crystal size of surficial halite is reduced by hygroscopic alteration. Efflorescent crusts extend the capillary fringe to the surface along vertical permeability pathways. When the water table is shallow, planar dissolution in the vadose zone removes all or most halite from successive thin depositional sequences and progressively disrupts strata consisting of clay or sulfate into irregular strata, stringers, isolated blebs, and, ultimately, 'blebby' laminae. With a deeper water table, point dissolution occurs along vertically oriented permeability pathways (e.g., polygonal margins) producing characteristic textures. Vertical pits, pipes, and macropores form first. Then the surface becomes slightly hummocky as point solution pathways to the water table widen and coalesce. A complex terrain of spires, hummocks, and columns develops and exhibits characteristic pods and lenses of fine halite surrounded by and containing solution lags of insoluble material. Relief is reduced by solution, and lenses and pods of fine halite become smaller and less common. Ultimately, halite is entirely removed leaving only insoluble material. Halite cements grow in the phreatic zone. Halite passively fills voids in more mechanically competent halite. Displacive halite cements dilate fabrics within less competent bedded halite. These textures can be integrated into an idealized lithologic sequence for ancient salt pan halite.

Stratigraphy of the Yucca Formation, Indio Mountains, west Texas  

SciTech Connect

The Indio Mountains are located 25 miles south of Van Horn, Texas, on the northwestern margin of the Chihuahua Tectonic Belt. The Indio Mountains are composed of Cretaceous sedimentary rocks deposited on the edge of the Chihuahua trough. The focus of this study, the Yucca conglomerate, is the oldest known Mesozoic rock in the region, although its unconformable base is not exposed within the Indio Mountains. This area has been affected by faulting associated with both the Chihuahua tectonic belt and the Rio Grande Rift. During summer 1992, the authors measured a stratigraphic section through the Yucca conglomerate, using a custom made Jacob's staff. The measured section is over 500 meters thick and was measured and described in 3 meter intervals. The section was measured up a single valley, and did contain some minor faults. This project had three objectives: (1) to examine variations in the sand/conglomerate ratio throughout the Yucca Fm.; (2) to examine variations in conglomerate clast composition using outcrop and thin section analysis; and, (3) ultimately, to compare this stratigraphic section with sections measured by Underwood (1962) in the Eagle Mountains and Devil's Ridge to the northwest. The sand/conglomerate ratio varies, with the proportion of sand increasing up section. At the base of the section, the rocks are mostly clast supported conglomerate interbedded with thin (12 cm) sand layers. The top of the section is dominated by sandstones with pebble stringers, with some massive sand layers over 6m thick. Few truly conglomeratic layers are present near the top of the section. The composition of clasts within the conglomerate also varies. The carbonate clasts are often preferentially eroded. The carbonate content increases up section.

Application of the method of effective potentials to a model for twinning in elastic materials  

SciTech Connect

We extend the method of effective potentials to systems with next-nearest-neighbor interactions, and apply it to a one-dimensional discrete model for twins in elastic materials. The energy of the system is given by H = +(..gamma../2) (u/sub n//sub +1/-2u/sub n/+u/sub n-1/)/sup 2/ -cosu/sub n/, where the first two terms model the elastic strain-dependent energy which we take to be in the form of a double well in the strains and the third term gives its dependence on the discretized strain gradients. The periodic potential in the last term is introduced to allow for additional interactions with a background such as a parent phase, grain boundaries, or another array of twins. We obtain the phase diagram and show that it consists of various modulated commensurate as well as incommensurate ground-state configurations. We find continuous phonon-driven transitions between the homogeneous and any modulated phase, an incomplete devil's staircase in a narrow region close to the homogeneous phase and first-order soliton-driven transitions between commensurate phases. The first-order transition lines end at triple points where three commensurate phases coexist. In contrast to other nonconvex models we do not find here any superdegenerate points. We give general arguments which exclude the existence of such points in the present model. Preliminary results obtained by driving the system are discussed. These consist of various metastable configurations exhibiting strong hysteretic variation with the driving force.
