Title: Diffusion and chaos from near AdS 2 horizons

Abstract

We calculate the thermal diffusivity D = $$\kappa/c_\rho$$ and butterfy velocity $$\upsilon_\beta$$ in holographic models that flow to $$AdS_2$$ x $R^d$ fixed points in the infra-red. We show that both these quantities are governed by the same irrelevant deformation of $$AdS_2$$ and hence establish a simple relationship between them. When this deformation corresponds to a universal dilaton mode of dimension $$\Delta$$ = 2 then this relationship is always given by D = $$\upsilon_B^2$$/(2$$\pi$$T).

  • We point out that the entropy of (near) extremal black holes can be interpreted as the entanglement entropy of dual conformal quantum mechanics via AdS{sub 2}/CFT{sub 1}. As an explicit example, we study near extremal Banados-Teitelboim-Zanelli black holes and derive this claim from AdS{sub 3}/CFT{sub 2}. We also analytically compute the entanglement entropy in the two dimensional CFT of a free Dirac fermion compactified on a circle at finite temperature. From this result, we clarify the relation between the thermal entropy and entanglement entropy, which is essential for the entanglement interpretation of black hole entropy.
  • Simultaneous Raman-Rayleigh-fluoresence measurements have been made in turbulent jet diffusion flames of CO/CH{sub 4}/N{sub 2} and CO/H{sub 2}/N{sub 2} fuel mixtures. Species mass fractions of CO, CO{sub 2}, CH{sub 4}, H{sub 2}, H{sub 2}O, O{sub 2} and N{sub 2} are obtained from the Raman data, density and temperature from the Rayleigh data, and the OH radical from the laser-induced fluorescence measurements. The fairly high N{sub 2} dilution, by suppressing chemiluminescence interference, results in improved quality Raman data. The extinction behavior of all the flames tested is qualitatively similar to that of diluted flames of CH{sub 4}: as the jet velocitymore » is increased, extinguished parcels appear more and more frequently in the region of highest mixing rates, until finally reaction downstream of this region is no longer sustained. For the CO/CH{sub 4}/N{sub 2} flames extinction occurs throughout the reactive zone, whilst for the CO/H{sub 2}/N{sub 2} flame, extinction is seen mainly on the lean side of stoichiometric composition. One effect of CH{sub 4} admixture is to narrow the reaction zone on the rich side through radical depletion by the fuel. As expected, it is found that the CO-CO{sub 2} conversion is far from being in partial equilibrium in these flames.« less
  • In this paper, surrogate models are iteratively built using polynomial chaos expansion (PCE) and detailed numerical simulations of a carbon sequestration system. Output variables from a numerical simulator are approximated as polynomial functions of uncertain parameters. Once generated, PCE representations can be used in place of the numerical simulator and often decrease simulation times by several orders of magnitude. However, PCE models are expensive to derive unless the number of terms in the expansion is moderate, which requires a relatively small number of uncertain variables and a low degree of expansion. To cope with this limitation, instead of using amore » classical full expansion at each step of an iterative PCE construction method, we introduce a mixed-integer programming (MIP) formulation to identify the best subset of basis terms in the expansion. This approach makes it possible to keep the number of terms small in the expansion. Monte Carlo (MC) simulation is then performed by substituting the values of the uncertain parameters into the closed-form polynomial functions. Based on the results of MC simulation, the uncertainties of injecting CO{sub 2} underground are quantified for a saline aquifer. Moreover, based on the PCE model, we formulate an optimization problem to determine the optimal CO{sub 2} injection rate so as to maximize the gas saturation (residual trapping) during injection, and thereby minimize the chance of leakage.« less
  • Carboxylic acid (HORc)-modified Ti(OR){sub 4} products were used to study the effect that similarly ligated species with substantially varied structures have on the final densification of the resultant ceramic (in this case TiO{sub 2}). The 1:1 stoichiometric products isolated from the reactions of [Ti({mu}-ONep)(ONep){sub 3}]{sub 2} (1, ONep = OCH{sub 2}CMe{sub 3}) and a variety of sterically hindered carboxylic acids [HORc: HOFc (HO{sub 2}CH), HOAc (HO{sub 2}CCH{sub 3}), HOPc (HO{sub 2}CCHMe{sub 2}), HOBc (HO{sub 2}CCMe{sub 3}), or HONc (HO{sub 2}CCH{sub 2}CMe{sub 3})] were identified by single-crystal X-ray diffraction and solid-state {sup 13}C MAS NMR spectroscopy at Ti{sub 3}({mu}{sub 3}-O)(OFc){sub 2}(ONep){submore » 8} (2), Ti{sub 3}({mu}{sub 3}-O)(OAc){sub 2}(ONep){sub 8} (3), Ti{sub 6}({mu}{sub 3}-O){sub 6}(OPc){sub 6}(ONep){sub 6} (4), Ti{sub 2}({mu}-OBc){sub 2}(ONep){sub 6} (5), and Ti{sub 3}({mu}{sub 3}-O)(ONc){sub 2}(ONep){sub 8} (6). Compounds 2, 3, and 6 adopt a triangular arrangement of Ti atoms linked by a {mu}{sub 3}-oxide moiety with ORc and ONep ligands supporting the basic framework. Compound 4 adopts a distorted, hexagon-prism geometry of two offset [Ti-O-]{sub 3} rings with each six-coordinated metal possessing a terminal ONep and two monodentate OPc ligands. The unique, nonesterified product 5 is dimeric with two {mu}-ONep, two unidentate bridging OBc, and two terminal ONep ligands. The solution behaviors of 2--6 were investigated by NMR experiments and were found to retain the solid-state structure in solution with a great deal of ligand rearrangement. Films of TiO{sub 2} were made from redissolved crystals of 2--6. The highest density TiO{sub 2} thin films were derived from the partially hydrolyzed, trinuclear, low-carbon-containing ONep complexes 2 and 3, as determined from ellipsometric data.« less
  • We report on the observation of spatiotemporal chaos in a multimode continuous Na/sub 2/ ring laser optically pumped by a single-mode Ar/sup +/ laser. Measurements of the intensity of the emitted beam at two different points of the beam cross section reveal different temporal behavior of those two signals. Power spectra, fractal dimensions, and correlations indicate that both signals are chaotic and are generated by a common attractor.
