Phase transitions in two-dimensional Z(N) vector models for N>4
O. Borisenko, V. Chelnokov, G. Cortese, R. Fiore, M. Gravina et al.
We investigate both analytically and numerically the renormalization group equations in two-dimensional (2D) Z(N) vector models. The position of the critical points of the two phase transitions for N>4 is established and the critical index nu is computed. For N=7 and 17 the critical points are locat ... [Phys. Rev.

Thermodynamics of ideal gas in doubly special relativity
Nitin Chandra and Sandeep Chatterjee
We study thermodynamics of an ideal gas in doubly special relativity. A new type of special functions (which we call incomplete modified Bessel functions) emerge. We obtain a series solution for the partition function and derive thermodynamic quantities. We observe that doubly special relativity the ... [Phys. Rev. D 85, 045012 ] published .
A first-principles density functional theory study of the electronic structural and thermodynamic properties of MZrO and MCO (M = Na, K) and their capabilities for CO capture
Yuhua Duan
Alkali metal zirconates could be used as solid sorbents for CO capture. The structural, electronic, and phonon properties of NaZrO, KZrO, NaCO, and KCO are investigated by combining the density functional theory with lattice phonon dynamics. The thermodynamics of CO absorption/desorption reactions o ... [J. Renewable Sustainable Energy 4, 013109 (2012)] published Wed Feb 8, 2012.
Phase Diagram and Density Large Deviations of a Nonconserving ABC Model
O. Cohen and D. Mukamel
The effect of particle-nonconserving processes on the steady state of driven diffusive systems is studied within the context of a generalized ABC model. It is shown that in the limit of slow nonconserving processes, the large deviation function of the overall particle density can be computed by maki ... [Phys. Rev. Lett. 108, 060602 ] published .

Nonequilibrium thermodynamics of feedback control
Takahiro Sagawa and Masahito Ueda
We establish a general theory of feedback control on classical stochastic thermodynamic systems and generalize nonequilibrium equalities such as the fluctuation theorem and the Jarzynski equality in the presence of feedback control with multiple measurements. Our results are generalizations of the p ... [Phys. Rev. E 85, 021104 ] published .
Ordering in ternary nitride semiconducting alloys
Michal Lopuszynski and Jacek A. Majewski
We present a thorough theoretical study of ordering phenomena in nitride ternary alloys GaInN, AlInN, and AlGaN. Using the Monte Carlo approach and energetics based on the Keating model, we analyze the influence of various factors on ordering in bulk crystals and epitaxial layers. We characterize th ... [Phys.

Different diffusive regimes, generalized Langevin and diffusion equations
A. A. Tateishi, E. K. Lenzi, L. R. da Silva, H. V. Ribeiro, S. Picoli, Jr. et al.
We investigate a generalized Langevin equation (GLE) in the presence of an additive noise characterized by the mixture of the usual white noise and an arbitrary one. This scenario lead us to a wide class of diffusive processes, in particular the ones whose noise correlation functions are governed by ... [Phys. Rev. E 85, 011147 ] published .
Efficiency and its bounds for thermal engines at maximum power using Newton's law of cooling
H. Yan and Hao Guo
We study a thermal engine model for which Newton's cooling law is obeyed during heat transfer processes. The thermal efficiency and its bounds at maximum output power are derived and discussed. This model, though quite simple, can be applied not only to Carnot engines but also to four other types of ... [Phys. Rev. E 85, 011146 ] published .
Generalized Pauli principle for particles with distinguishable traits
Dan Liu, Jared Vanasse, Gerhard Muller, and Michael Karbach
The s=(3/2) Ising spin chain with uniform nearest-neighbor coupling, quadratic single-site potential, and magnetic field is shown to be equivalent to a system of 17 species of particles with internal structure. The same set of particles (with different energies) is shown to generate the spectrum of ... [Phys. Rev. E 85, 011144 ] published .
Approach to typicality in many-body quantum systems
Shawn Dubey, Luciano Silvestri, Justin Finn, Sai Vinjanampathy, and Kurt Jacobs
The recent discovery that for large Hilbert spaces, almost all (that is, typical) Hamiltonians have eigenstates that place small subsystems in thermal equilibrium, has shed much light on the origins of irreversibility and thermalization. Here we give numerical evidence that many-body lattice systems ... [Phys. Rev. E 85, 011141 ] published .
Solvent-induced current-voltage hysteresis and negative differential resistance in molecular junctions
Alan A. Dzhioev and D. S. Kosov
We consider a single molecule circuit embedded into solvent. The Born dielectric solvation model is combined with Keldysh nonequilibrium Green's functions to describe the electron-transport properties of the system. Depending on the dielectric constant, the solvent induces multiple nonequilibrium st ... [Phys. Rev. B 85, 033408 ] published .
Restoration of symmetry in the spectrum of the bilayer Heisenberg antiferromagnet
C. J. Hamer, J. Oitmaa, and Zheng Weihong
The longitudinal mode in the Heisenberg model on a bilayer square lattice is studied using series expansion methods. It is demonstrated numerically that the longitudinal mode becomes degenerate with the magnon modes at the quantum phase transition between Neel and dimerized phases, thus forming a sp ... [Phys. Rev.

Atomic ordering in Au-(42 to 50) at.% Pd: A diffuse scattering and first-principles investigation
B. Schonfeld, C. R. Sax, and A. V. Ruban
Atomic ordering in Au-Pd alloys was studied by diffuse x-ray scattering and first-principles methods. Diffuse scattering was done of a single crystal of Au-48 at.% Pd that was aged at 703 K for 24 days. The weakly modulated short-range-order scattering exhibits diffuse maxima with an incommensurate ... [Phys. Rev. B 85, 014204 ] published .

Conditions for the validity of the quantum Langevin equation
J. Frenkel and J. C. Taylor
From microscopic models, a Langevin equation can, in general, be derived only as an approximation. Two possible conditions to validate this approximation are studied. One is, for a linear Langevin equation, that the frequency of the Fourier transform should be close to the natural frequency of the s ... [Phys. Rev. E 85, 011135 ] published .
Superfluid-insulator transition of ultracold bosons in disordered one-dimensional traps

We derive an effective quantum Josephson array model for a weakly interacting one-dimensional condensate that is fragmented into weakly coupled puddles by a disorder potential. The distribution of coupling constants, obtained from first principles, indicates that weakly interacting bosons in a disor ... [Phys. Rev. B 85, 024531 ] published .
