2-TEMPERATURE NONEQUILIBRIUM ISING-MODELS

We present results from a computational study of a class of 2D two-tem perature non-equilibrium Ising models. In these systems the dynamics i s a local competition of two equilibrium dynamics at different tempera tures. We analyzed non-equilibrium versions of Metropolis, heat bath/G lauber and Swendsen-Wang dynamics and found strong evidence that some of these dynamics have the same critical exponents and belong to the s ame universality class as the equilibrium 2D Ising model.
