We investigate theoretically and via computer simulation the stationary nonequilibrium states of a stochastic lattice gas under the influence of a uniform external fieldE. The effect of the field is to bias jumps in the field direction and thus produce a current carrying steady state. Simulations on a periodic 30 × 30 square lattice with attractive nearest-neighbor interactions suggest a nonequilibrium phase transition from a disordered phase to an ordered one, similar to the para-to… 

Phase transitions in a driven lattice gas in two planes

We report on a Monte Carlo study of ordering in a nonequilibrium system. The system is a lattice gas that comprises two equal, parallel square lattices with stochastic particle-conserving

Continuous-time Monte Carlo and spatial ordering in driven lattice gases: Application to driven vortices in periodic superconducting networks

We consider the two-dimensional 2D classical lattice Coulomb gas as a model for magnetic field induced vortices in 2D superconducting networks. Two different dynamical rules are introduced to

Nonequilibrium phase transition in stochastic lattice gases: Simulation of a three-dimensional system

We report results of computer simulations of a three-dimensional lattice gas of interacting particles subject to a uniform external fieldE. The dynamics of the system is given by hoppings of

The fast rate limit of driven diffusive systems

We study the stationary nonequilibrium states of the van Beijeren/Schulman model of a driven lattice gas in two dimensions. In this model, jumps are much faster in the direction of the driving force

Phase transitions in nonequilibrium stochastic particle systems with local conservation laws

Stochastic particle systems far from equilibrium show a great variety of critical phenomena already in one dimension. We concentrate on models where the number of particles is locally conserved. In

Non-equilibrium phase transition in a two-temperature lattice gas

A two-temperature lattice gas model with repulsive nearest-neighbour interactions is studied using Monte Carlo simulations and dynamical mean-field approximations. The evolution of the

Steady-state electrical conduction in the periodic Lorentz gas

We study nonequilibrium steady states in the Lorentz gas of periodic scatterers when an electric external field is applied and the particle kinetic energy is held fixed by a “thermostat” constructed

Nonequilibrium chemical potentials of steady-state lattice gas models in contact: A large-deviation approach.

A general framework to describe the stationary state of two driven systems exchanging particles or mass through a contact, in a slow exchange limit, using an exactly solvable driven lattice gas model and the Katz-Lebowitz-Spohn model to evaluate the chemical potential.

Description of far-from-equilibrium processes by mean-field lattice gas models

Mean-field kinetic equations are a valuable tool to study the atomic dynamics and spin dynamics of simple lattice gas and Ising models. They can be derived from the microscopic master equation of the

The exact solution of the three-dimensional Ising model of a ferromagnetic presents difficulties of a very fundamental nature. It therefore seems that the most reliable information on the behaviour

Monte Carlo calculation of the simultaneous ionic conductivity and tracer diffusion in β-alumina

Abstract A new Monte Carlo method is described for simultaneously calculating the charge carrier and tracer correlation factors. Application is made to β-alumina where the conduction plane is

Theoretical models for superionic conductors

Abstract The present theoretical understanding of various properties of superionic conductors is reviewed. Emphasis is put on their treatment as classical many-particle systems and on the analysis of

Transport coefficients from computer experiments: A stochastic Ising model

Transport coefficients for a two-dimensional stochastic Ising model with conserved energy and magnetization are calculated by computer simulation. Transport coefficients are derived from the

Crystal statistics. I. A two-dimensional model with an order-disorder transition

The partition function of a two-dimensional "ferromagnetic" with scalar "spins" (Ising model) is computed rigorously for the case of vanishing field. The eigenwert problem involved in the

We prove analyticity of the correlation functions for classical lattice systems, including “continuous-spin” systems, at high temperatures and in strong external fields. For systems whose
