Dynamic Phase Transition, Universality, and Finite-size Scaling in the Two-dimensional Kinetic Ising Model in an Oscillating Field

open access: yes, 2000
We study the two-dimensional kinetic Ising model below its equilibrium critical temperature, subject to a square-wave oscillating external field. We focus on the multi-droplet regime where the metastable phase decays through nucleation and growth of many

A quantitative model for evaluating the impact of volatile oil non-equilibrium phase transition on degassing

open access: yesPetroleum Exploration and Development, 2012
To quantitatively evaluate the impact of non-equilibrium phase transition on degassing in an oil-gas system and accurately determine the bubble point pressure of the system with different oil rates, a model, which takes the influence of pressure drop and

Phase transition dynamics in the hot Abelian Higgs model [PDF]

open access: yes, 2001
We present a detailed numerical study of the equilibrium and non-equilibrium dynamics of the phase transition in the finite-temperature Abelian Higgs model.

Application of near critical behavior of equilibrium ratios to phase equilibrium calculations

open access: yesOil & Gas Science and Technology, 2019
We examine the asymptotic behavior of the equilibrium ratios (Ki) near the convergence locus in the pressure-temperature plane. When the Equation of State (EoS) is analytical, which is the case of most EoS of engineering purpose, Ki tends towards unity ...

Non-equilibrium topological phase transitions in two-dimensional optical lattices [PDF]

open access: yes, 2014
Recently, concepts of topological phases of matter are extended to non-equilibrium systems, especially periodically driven systems. In this paper, we construct an example which shows non-equilibrium topological phase transitions using ultracold fermions ...

Phase Transitions in Equilibrium and Non-Equilibrium Models on Some Topologies

open access: yesEntropy, 2016
On some regular and non-regular topologies, we studied the critical properties of models that present up-down symmetry, like the equilibrium Ising model and the nonequilibrium majority vote model. These are investigated on networks, like Apollonian (AN),

Multi-Phase Equilibrium of Crystalline Solids

open access: yes, 1999
A continuum model of crystalline solid equilibrium is presented in which the underlying periodic lattice structure is taken explicitly into account. This model also allows for both point and line defects in the bulk of the lattice and at interfaces, and ...

Quasi-binary amorphous phase in a 3D system of particles with repulsive-shoulder interactions [PDF]

open access: yes, 2007
We report a computer-simulation study of the equilibrium phase diagram of a three-dimensional system of particles with a repulsive step potential. Using free-energy calculations, we have determined the equilibrium phase diagram of this system.

Phase Diagram for a 2-D Two-Temperature Diffusive XY Model [PDF]

open access: yes, 2010
Using Monte Carlo simulations, we determine the phase diagram of a diffusive two-temperature XY model. When the two temperatures are equal the system becomes the equilibrium XY model with the continuous Kosterlitz-Thouless (KT) vortex-antivortex ...

Equilibrium phase transitions in a porous medium [PDF]

open access: yesPhysical Review B, 1996
Static critical phenomena of a three-dimensional Ising model confined in a porous medium made by spinodal decomposition have been studied using large-scale Monte Carlo simulations. We thus examine the influence of the geometry of Vycor-like materials on phase transitions.
