Abstract

Two-dimensional lattice-gas models with attractive interactions and particle-conserving hopping dynamics under the influence of a very large external electric field along a principal axis are studied in the case of off-critical densities. We describe the corresponding nonequilibrium first-order phase transitions, evaluate coexistence and spinodal lines, and make some comparisons with experimental observations on fast ionic conductors.

Key words

Stochastic lattice-gas model stationary nonequilibrium states fast ionic conductors metastability nonequilibrium first-order phase transitions
