The Wheeler - DeWitt Quantum Geometrodynamics: its fundamental problems and tendencies of their resolution  

E-Print Network [OSTI]

The paper is devoted to fundamental problems of the Wheeler - DeWitt quantum geometrodynamics, which was the first attempt to apply quantum principles to the Universe as a whole. Our purpose is to find out the origin of these problems and follow up their consequences. We start from Dirac generalized Hamiltonian dynamics as a cornerstone on which the Wheeler - DeWitt theory is based. We remind the main statements of the famous DeWitt's paper of 1967 and discuss the flaws of the theory: the well-known problem of time, the problem of Hilbert space and others. In the concluding part of the paper we consider new tendencies and approaches to quantum geometrodynamics appeared in the last decade.

An electromagnetic perpetuum mobile?  

E-Print Network [OSTI]

A charge moving freely in orbit around the Earth radiates according to Larmor's formula. If the path is closed, it would constitute a perpetuum mobile. The solution to this energy paradox is found in an article by C. M. DeWitt and B. DeWitt from 1964. The main point is that the equation of motion of a radiating charge is modified in curved spacetime. In the present article we explain the physics behind this modification, and use the generalized equation to solve the perpetuum mobile paradox.

Coherences of accelerated detectors and the local character of the Unruh effect  

E-Print Network [OSTI]

We study the locality of the acceleration temperature in the Unruh effect. To this end, we develop a new formalism for the modeling of macroscopic irreversible detectors. In particular, the formalism allows for the derivation of the higher-order coherence functions, analogous to the ones employed in quantum optics, that encode temporal fluctuations and correlations in particle detection. We derive a causal and approximately local-in-time expression for an Unruh-Dewitt detector moving in a general path in Minkowski spacetime. Moreover, we derive the second-order coherence function for uniformly accelerated Unruh-Dewitt detectors. We find that the fluctuations in detection time for a single Unruh-Dewitt detector are thermal. However, the correlations in detection-time between two Unruh-Dewitt detectors with the same acceleration but separated by a finite distance are not thermal. This result suggests that the Unruh effect is fundamentally local, in the sense that the notion of acceleration temperature applies only to the properties of local field observables.

"Instantaneous superluminality" in a bimetallic wire consisting of a superconducting aluminum wire plated with a thick copper covering  

E-Print Network [OSTI]

Maxwell's equations applied to a superconducting wire (aluminum) covered with a thick nonsuperconducting sheath (copper), in combination with the superfluid velocity equation for Cooper pairs which obeys DeWitt's minimal coupling rule, implies an instantaneous streamline flow that leads to the phenomenon of "instantaneous superluminality," in which a Cooper pair can disappear from the left end of the wire and instantaneously reappear at the right end of the wire. Relativistic causality is not violated by this superluminal phenomenon, which involves analytic, finite bandwidth waveforms whose spectrum lies below the BCS gap frequency. Experiments are proposed to test these ideas.

Grounds for Quantum Geometrodynamics in an extended phase space and its cosmological consequences  

E-Print Network [OSTI]

Quantum geometrodynamics (QGD) in extended phase space essentially distinguished from the Wheeler - DeWitt QGD is proposed. The grounds for constructing a new version of quantum geometrodynamics are briefly discussed. The main part in the proposed version of QGD is given to the Schrodinger equation for a wave function of the Universe. The Schrodinger equation carries information about a chosen gauge condition which fixes a reference system. The reference system is represented by a continual medium that can be called ``the gravitational vacuum condencate". A solution to the Schrodinger equation contains information about the integrated system ``a physical object + observation means (the gravitational vacuum condensate)". It may be demonstrated that the gravitational vacuum condensate appears to be a cosmological evolution factor.

Quantum geometrodynamics creates new problems  

E-Print Network [OSTI]

The development of last years in quantum geometrodynamics highlights new problems which were not obvious in its first formulation proposed by Wheeler and DeWitt. At the first stage the main task was to apply known quantization schemes to gravitational field or a certain cosmological model. This way has led to the realization of the fact that a quantum description of the Universe is impossible without implicit or explicit indication to a reference frame presented by some medium, filling the whole Universe, with its own equation of state and thermodynamical properties. Thus the questions arise, should one seek for a "privileged" reference frame or consider all the variety of gauge conditions and appropriate solutions for the wave function? It is worth noting that thermodynamical properties of such a quantum Universe would also depend on a chosen reference frame to some extent. So, we need a self-consistent quantum theoretical and thermodynamical description of the Universe.

Quantum cosmological solutions: their dependence on the choice of gauge conditions and physical interpretation  

E-Print Network [OSTI]

In "extended phase space" approach to quantum geometrodynamics numerical solutions to Schrodinger equation corresponding to various choice of gauge conditions are obtained for the simplest isotropic model. The "extended phase space" approach belongs to those appeared in the last decade in which, as a result of fixing a reference frame, the Wheeler - DeWitt static picture of the world is replaced by evolutionary quantum geometrodynamics. Some aspects of this approach were discussed at two previous PIRT meetings. We are interested in the part of the wave function depending on physical degrees of freedom. Three gauge conditions having a clear physical meaning are considered. They are the conformal time gauge, the gauge producing the appearance of Lambda-term in the Einstein equations, and the one covering the two previous cases as asymptotic limits. The interpretation and discussion of the obtained solutions is given.

Cosmological solutions for the Universe filled with matter in various states and gauge invariance  

E-Print Network [OSTI]

We explore at phenomenological level a model of the Universe filled with various kinds of matter characterized by different equations of state. We show that introducing of each kind of matter is equivalent to a certain choice of a gauge condition, the gauge condition describing a medium with a given equation of state. The case of a particular interest is when one kind of matter (de Sitter false vacuum) dominates at the early stage of the Universe evolution while another kind (radiation, or ultrarelativistic gas) dominates at its later stage. We can, therefore, consider different asymptotic regimes for the early and later stages of the Universe existence. These regimes are described by solutions to the Wheeler - DeWitt equation for the Universe with matter in that given state, and, at the same time, in the "extended phase space" approach to quantum geometrodynamics the regimes are described by solutions to a Schrodinger equation associated with a choice of some gauge condition. It is supposed that, from the viewpoint of the observer located at the later stage of the Universe evolution, solutions for a Lambda-dominated early Universe would decay.

The "extended phase space" approach to quantum geometrodynamics: what can it give for the development of quantum gravity?  

E-Print Network [OSTI]

The talk is devoted to the "extended phase space" approach to Quantum Geometrodynamics. The premises that have led to the formulation of this approach are briefly reviewed, namely, non-trivial topology of the Universe which implies the absence of asymptotic states, in contrast to situations one usually deals in ordinary quantum field theory; parametrization noninvariance in the Wheeler - DeWitt theory; the problem of time and the absence of dynamical evolution. Then we discuss the main features of the approach: Hamiltonian dynamics in extended phase space, gauge-dependent Schrodinger equation for the wave function of the Universe, the description of quantum Universe from the viewpoint of observers in a wide enough class of reference frames. After all, we analyse problems arising in this approach: the structure of Hilbert space in Quantum Geometrodynamics, the relations between solutions for the wave function of the Universe corresponding to various reference frames, properties of a medium to be necessary to fix a reference frame, the transition to classical limit.

The formulation of General Relativity in extended phase space as a way to its quantization  

E-Print Network [OSTI]

Our attempts to find an explanation for quantum behavior of the Early Universe appeal, as a rule, to the Wheeler - DeWitt Quantum Geometrodynamics which relies upon Hamiltonian formulation of General Relativity proposed by Arnowitt, Deser and Misner (ADM). In spite of the fact that the basic ideas of this approach were put forward about fifty years ago, even now we do not have clear understanding what Hamiltonian formulation of General Relativity must be. An evidence for it gives a recent paper by Kiriushcheva and Kuzmin [arXiv:0809.0097], where the authors claim that the formulation by ADM and that by Dirac made in his seminal work of 1958 are not equivalent. If so, we face the question what formalism should be chosen. Another problem is that we need a well-grounded procedure of constructing a generator of transformations in phase space for all gravitational variables including gauge ones. It suggests the notion of extended phase space. After analyzing the situation, we show that Hamiltonian formulation in extended phase space is a real alternative to Dirac and ADM formulations and can be constructed to be equivalent to the original (Lagrangian) formulation of General Relativity. Quantization in extended phase space is straightforward and leads to a new description of quantum Universe in which an essential place is given to gauge degrees of freedom.

Hamiltonian formulation of General Relativity 50 years after the Dirac celebrated paper: do unsolved problems still exist?  

E-Print Network [OSTI]

About 50 years ago, in 1958, Dirac published his formulation of generalized Hamiltonian dynamics for gravitation. Several years later Arnowitt, Deser and Misner (ADM) proposed their description of the dynamics of General Relativity which became a basis of the Wheeler - DeWitt Quantum Geometrodynamics. There exist also other works where the Hamiltonian formulation of gravitational theory was discussed. In spite of decades passed from the famous papers by Dirac and ADM, there are unsolved problems. Namely, are the Dirac and ADM formulations equivalent to each other? Are these formulations equivalent to the original (Lagrangian) Einstein theory? Is the group of transformation in phase space the same as the group of gauge transformation of the Einstein theory? What are rules according to which a generator of transformations in phase space should be constructed? Let us mention also another approach based on extended phase space where gauge degrees of freedom are treated on the equal ground with physical degrees of freedom. Our purpose is to review the above questions and to demonstrate advantages of the extended phase space approach by the example of a simple model with finite number degrees of freedom.

Environmental analysis of geopressured-geothermal prospect areas, De Witt and Colorado counties, Texas. Final report, March 1 - August 31, 1979  

SciTech Connect (OSTI)

Information collected and analyzed for a preliminary environmental analysis of geopressured geothermal prospect areas in Colorado and DeWitt Counties, Texas is presented. Specific environmental concerns for each geopressured geothermal prospect area are identified and discussed. Approximately 218 km/sup 2/(85 mi/sup 2/) were studied in the vicinity of each prospect area to: (1) conduct an environmental analysis to identify more and less suited areas for geopressured test wells; and (2) provide an environmental data base for future development of geopressured geothermal energy resources. A series of maps and tables are included to illustrate environmental characteristics including: geology, water resources, soils, current land use, vegetation, wildlife, and meteorological characteristics, and additional relevant information on cultural resources, power- and pipelines, and regulatory agencies. A series of transparent overlays at the scale of the original mapping has also been produced for the purposes of identifying and ranking areas of potential conflict between geopressured geothermal development and environmental characteristics. The methodology for ranking suitability of areas within the two prospect areas is discussed in the appendix. (MHR)

The Census Taker's Hat  

E-Print Network [OSTI]

If the observable universe really is a hologram, then of what sort? Is it rich enough to keep track of an eternally inflating multiverse? What physical and mathematical principles underlie it? Is the hologram a lower dimensional quantum field theory, and if so, how many dimensions are explicit, and how many "emerge?" Does the Holographic description provide clues for defining a probability measure on the Landscape? The purpose of this lecture is first, to briefly review a proposal for a holographic cosmology by Freivogel, Sekino, Susskind, and Yeh (FSSY), and then to develop a physical interpretation in terms of a "Cosmic Census Taker:" an idea introduced in reference [1]. The mathematical structure--a hybrid of the Wheeler DeWitt formalism and holography--is a boundary "Liouville" field theory, whose UV/IR duality is closely related to the time evolution of the Census Taker's observations. That time evolution is represented by the renormalization-group flow of the Liouville theory. Although quite general, the Census Taker idea was originally introduced in \\cite{shenker}, for the purpose of counting bubbles that collide with the Census Taker's bubble. The "Persistence of Memory" phenomenon discovered by Garriga, Guth, and Vilenkin, has a natural RG interpretation, as does slow roll inflation. The RG flow and the related C-theorem are closely connected with generalized entropy bounds.

Entanglement Entropy of the Early Universe in Generalized Chaplygin Gas Model  

E-Print Network [OSTI]

We provide an explicit calculation of the evolution of the cosmic entanglement entropy in the early universe before the matter dominant era. This is made possible by invoking the generalized Chaplygin gas (GCG) model, which has the advantage of preserving unitarity and providing a smooth transition between the inflation epoch and the radiation dominant era. The dynamics of the universe is described by the quantization in the minisuperspace of the GCG model, following the prescription proposed by Wheeler and DeWitt. Two sources of contribution to the cosmic entanglement entropy are considered: one from the homogeneous background where the observable and the unobservable regions of the universe are entangled and the other from the inhomogeneous cosmological perturbations where different modes are entangled. We find that the homogeneous contribution grows exponentially at the very beginning of the inflation, but decreases during the radiation dominant era. Conversely, that from the cosmological perturbation is found to decrease at first and then increase after reaching a minimum value. The net result is that the total entanglement entropy reaches a minimum at an early stage of the inflation and then increases throughout most of the inflation and the entire radiation dominant era.

The dynamics of the early universe and the initial conditions for inflation in a model with radiation and a Chaplygin gas  

E-Print Network [OSTI]

The modeling of the early universe is done through the quantization of a Friedmann-Robertson-Walker model with positive curvature. The material content consists of two fluids: radiation and Chaplygin gas. The quantization of these models is made by following the Wheeler and DeWitt's prescriptions. Using the Schutz formalism, the time notion is recovered and the Wheeler-DeWitt equation transforms into a time dependent Schr\\"{o}dinger equation, which rules the dynamics of the early universe, under the action of an effective potential $V_{ef}$. Using a finite differences method and the Crank-Nicholson scheme, in a code implemented in the program OCTAVE, we solve the corresponding time dependent Schr\\"{o}dinger equation and obtain the time evolution of a initial wave packet. This wave packet satisfies appropriate boundary conditions. The calculation of the tunneling probabilities shows that the universe may emerge from the Planck era to an inflationary phase. It also shows that, the tunneling probability is a function of the mean energy of the initial wave packet and of two parameters related to the Chaplygin gas. We also show a comparison between these results and those obtained by the WKB approximation.

A view on the problems of Quantum Gravity  

E-Print Network [OSTI]

The existing approaches to quantization of gravity aim at giving quantum description of 3-geometry following to the ideas of the Wheeler -- DeWitt geometrodynamics. In this description the role of gauge gravitational degrees of freedom is missed. A probable alternative is to consider gravitational dynamics in extended phase space, taking into account the distinctions between General Relativity and other field theories. The formulation in extended phase space leads to some consequences at classical and quantum levels. At the classical level, it ensures that Hamiltonian dynamics is fully equivalent to Lagrangian dynamics, and the algebra of Poisson brackets is invariant under reparametrizations in a wide enough class including reparametrizations of gauge variables, meantime in the canonical Dirac approach the constraints' algebra is not invariant that creates problems with quantization. At the quantum level, the approach come to the description in which the observer can see various but complementary quantum gravitational phenomena in different reference frames that answers the spirit of General Relativity and Quantum Theory. Though until now the approach was applied to General Relativity in its original formulations, its implementation in different trends, including Quantum Loop Gravity or some other representations of gravitational variables, would also be of interest.

MTBE -- A global perspective  

SciTech Connect (OSTI)

Methyl tertiary butyl ether (MTBE) is a major and familiar component of Reformulated and Oxygenated gasoline in the US. As such, it is essential to the success of the Clean Air Act programs now reaching a crescendo in major urban areas. In less than ten years, US MTBE capacity has grown from about 4,000 B/D to more than 200,000 B/D. Outside of the USA, its role is less widely understood. Although MTBE markets elsewhere are much less driven by legislation, they have seen the same spectacular growth prospects. Overall, about as much MTBE is used today overseas as in the US. To date, this has to be one of the petrochemical industry`s major success stories. Yet today, the MTBE industry stands at a crossroads, with the direction of future development uncertain at best. DeWitt`s gasoline and oxygenates team has closely observed the ups and downs of this market during most of its turbulent history. In this paper, the authors shall try to set down the major developments and prospects, with the personal familiarity of having been there when things changed. The story begins with a brief historical sketch, leading up to the identification of four critical periods in which major changes took place. The causes of today`s uncertainty lie in all of these stages, and are in a very real sense an example of the ``Law of Unintended consequences.`` Having set the stage, a cautious set of predictions will be put forth. These are neither as promising as proponents would like, nor as unpromising as some would tend to believe.

DEVELOPMENT OF A MUD-PULSE HIGH-TEMPERATURE MEASUREMENT-WHILE-DRILLING (MWD) SYSTEM  

SciTech Connect (OSTI)

The overall program objective is to develop a mud-pulse measurement-while-drilling (MWD) tool for oil and gas drilling operations that can be used where downhole temperatures are as high as 195 C (383 F). The work was planned to be completed in two phases: Phase I and an optional Phase II. The objectives of Phase I were first to identify critical components of existing MWD systems that can or cannot operate at 195 C. For components not able to meet the higher standard, one of several strategies was pursued: (1) locate high-temperature replacement components, (2) develop new designs that eliminate the unavailable components, or (3) use cooling to keep components at acceptable operating temperatures (under 195 C). New designs and components were then tested under high temperatures in the laboratory. The final goal of Phase I was to assemble two high-temperature MWD prototype tools and test each in at least one low-temperature well to verify total system performance. Phase II was also envisioned as part of this development. Its objective would be to test the two new high-temperature MWD prototype tools in wells being drilled in the United States where the bottom-hole temperatures were 195 C (or the highest temperatures attainable). The high-temperature MWD tool is designed to send directional and formation data to the surface via mud pulses, to aid in the drilling of guided wellbores. The modules that comprise the tool are housed in sealed barrels that protect the electronics from exposure to down-hole fluids and pressures. These pressure barrels are hung inside a non-magnetic collar located above the drilling assembly. A number of significant accomplishments were achieved during the course of the Phase I project, including: (1) Tested two MWD strings for function in an oven at 195 C; (2) Conducted field test of prototype 195 C MWD tool (at well temperatures up to 140-180 C); (3) Tested ELCON hybrid chip with processor, clock, and memory in a custom package for 700 hours at 200 C; (4) Contracted with APS Technology to conduct study of thermoelectric cooling of downhole electronics; (5) Conducted successful Peltier cooling test with APS Technology; (6) Tested and improved the electronics of Sperry Sun's Geiger Muller-based gamma detector for operation at 195 C; (7) Developed two high-temperature magnetometers (one in-house, one with Tensor); and (8) Encouraged outside source to develop lithium/magnesium high-temperature batteries (operating temperature of 125 to 215 C). One of this project's greatest achievements was improvement in Sperry Sun's current tool with changes made as a direct result of work performed under this project. These improvements have resulted in longer life and a more robust MWD tool at the previous temperature rating of 175 C, as well as at higher temperatures. A field test of two prototype 195 C MWD tools was conducted in Lavaca County, Texas. The purpose of this operation was to provide directional services on a sidetrack of a straight hole. The sidetrack was to intersect the formation up-dip above the water/gas interface. In addition, the gamma tool provided formation data including seam tops and thickness. Results from these field tests indicate progress in the development of a 195 C tool. Although the pulsers failed downhole in both tools, failure of the pulsers was determined to be from mechanical rather than electrical causes. Analysis of the economics of the 195 C tool highlights the greatest obstacle to future commercialization. Costs to screen individual components, then subassemblies, and finally completed tools for high-temperature operations are very high. Tests to date also show a relatively short life for high-temperature tools--on the order of 300 hours. These factors mean that the daily cost of the tool will be higher (3 to 5 times more) than a conventional tool.
