Interfaces in Driven Diffusive Systems

Abstract:   Like the Ising model for phase transitions, the driven lattice gas was introduced as a non-trivial, yet simple, testing ground for understanding fundamental issues of statistical mechanics of non-equilibrium steady states. In additions to many surprising properties displayed in bulk, the interface between co-existing phases at low temperatures also offers considerable challenges. Examples include anomalous height-height correlations and serious coupling to bulk degrees of freedom. After presenting the driven lattice gas and some of its singular bulk behavior, I will focus on the current status of the interfacial properties.
