Nonequilibrium phase transition in the case of correlated noises

Abstract

We consider the nonequilibrium phase transition in the case of correlated noises. A spatially extended model driven by the correlated noises is studied. By the Weiss mean-field approximation, we find that the correlation between the additive and multiplicative noises has an effect on the phase transition. The phase transition possesses some similar characteristics to the one of Van den Broeck, Parrondo, and Toral [Phys. Rev. Lett. 73, 3395 (1994)]. In addition, we investigate the effect of the additive noise on the phase transition. \textcopyright{} 1996 The American Physical Society.
