Adsorption of superheavy elements on metal surfaces
C. Sarpe-Tudoran, B. Fricke, J. Anton, and V. Persina
Fully relativistic four-component density functional theory with the general gradient approximation calculations have been performed to determine the adsorption energy and position of the superheavy element 112 on a Au surface. Extended cluster as well as embedded cluster calculations were used to s ... [J. Chem. Phys. 126, 174702 (2007)] published Tue May 1, 2007.
Thermal quantum electrodynamics of nonrelativistic charged fluids
Pascal R. Buenzli, Philippe A. Martin, and Marc D. Ryser
The theory relevant to the study of matter in equilibrium with the radiation field is thermal quantum electrodynamics (TQED). We present a formulation of the theory, suitable for nonrelativistic fluids, based on a joint functional integral representation of matter and field variables. In this formal ... [Phys. Rev. E 75, 041125 (2007)] published Mon Apr 30, 2007.
Characteristics of deterministic and stochastic sandpile models in a rotational sandpile model
S. B. Santra, S. Ranjita Chanu, and Debabrata Deb
Rotational constraint representing a local external bias generally has a nontrivial effect on the critical behavior of lattice statistical models in equilibrium critical phenomena. In order to study the effect of rotational bias in an out-of-equilibrium situation like self-organized criticality, a t ... [Phys. Rev. E 75, 041122 (2007)] published Mon Apr 30, 2007.
Coarsening of ``clouds'' and dynamic scaling in a far-from-equilibrium model system
D. A. Adams, B. Schmittmann, and R. K. P. Zia
A two-dimensional lattice gas of two species, driven in opposite directions by an external force, undergoes a jamming transition if the filling fraction is sufficiently high. Using Monte Carlo simulations, we investigate the growth of these jams (``clouds''), as the system approaches a nonequilibriu ... [Phys. Rev. E 75, 041123 (2007)] published Mon Apr 30, 2007.
Central limit behavior of deterministic dynamical systems
Ugur Tirnakli, Christian Beck, and Constantino Tsallis
We investigate the probability density of rescaled sums of iterates of deterministic dynamical systems, a problem relevant for many complex physical systems consisting of dependent random variables. A central limit theorem (CLT) is valid only if the dynamical system under consideration is sufficient ... [Phys. Rev. E 75, 040106 (2007)] published Mon Apr 30, 2007.
Computational study of the melting-freezing transition in the quantum hard-sphere system for intermediate densities. I. Thermodynamic results
Luis M. Sese
The points where the fluid-solid (face-centered-cubic) transition takes place in the quantum hard-sphere system, for reduced densities 0.85>rho[sub N][sup *]>0.5 (reduced de Broglie wavelengths lambda[sub B][sup *]<=0.8), have been determined via calculations of Helmholtz free energies. A number of ... [J. Chem. Phys. 126, 164508 (2007)] published Mon Apr 30, 2007.
Computational study of the melting-freezing transition in the quantum hard-sphere system for intermediate densities. II. Structural features

Optimal fluctuation approach to a directed polymer in a random medium
I. V. Kolokolov and S. E. Korshunov
A modification of the optimal fluctuation approach is applied to study the tails of the free-energy distribution function P[sub L](F) for an elastic string in quenched disorder both in the regions of the universal behavior of P[sub L](F) and in the regions of large fluctuations, where the behavior o ...

Ultracold Bose Gases in 1D Disorder: From Lifshits Glass to Bose-Einstein Condensate
P. Lugan, D. Clement, P. Bouyer, A. Aspect, M. Lewenstein et al.
We study an ultracold Bose gas in the presence of 1D disorder for repulsive interatomic interactions varying from zero to the Thomas-Fermi regime. We show that for weak interactions the Bose gas populates a finite number of localized single-particle Lifshits states, while for strong interactions a d ... [Phys. Rev. Lett. 98, 170403 (2007)] published Fri Apr 27, 2007.
Holographic Quantum Statistics from Dual Thermodynamics
Csaba Balazs and Istvan Szapudi
We propose dual thermodynamics corresponding to black hole mechanics with the identifications E[prime] --> A/4, S[prime] --> M, and T[prime] --> T[sup 1] in Planck units. Here A, M and T are the horizon area, mass and Hawking temperature of a black hole and E[prime], S[prime] and T[prime] are the en ... [AIP Conf. Proc. 903, 560 (2007)] published Fri Apr 27, 2007.
The Bonding Forces In Liquid Metals And Ultrasonic Field Action
Luminita Moraru and Gabriel Murariu
The understanding of the liquid metals properties is still imperfect. Assuming that the liquids are isotropic and show some elasticity properties, there are no physical reasons for rejecting the applicability of the fundamental ideas of the Debye theory to the description of the properties of liquid ...
