Inequivalence of Dynamical Ensembles in a Generalised Driven Diffusive Lattice Gas
arXiv:cond-mat/9910494
Abstract
We generalise the Driven Diffusive Lattice Gas (DDLG) model by using a combination of Kawasaki and Glauber dynamics. We find via Monte Carlo simulations and perturbation studies that the simplest possible generalisation of the equivalence of the canonical and grand-canonical ensembles, which holds in equilibrium, does not apply for this class of nonequilibrium systems.
