Nonequilibrium transitions induced by multiplicative noise
Genovese, Walter; Muñoz, Miguel Angel; Sancho, José M.
Universitat de Barcelona
A simple model exhibiting a noise-induced ordering transition (NIOT) and a noise-induced disordering transition (NIDT), in which the noise is purely multiplicative, is presented. Both transitions are found in two dimensions as well as in one dimension. We show analytically and numerically that the critical behavior of these two transitions is described by the so called multiplicative noise (MN) universality class. A computation of the set of critical exponents is presented in both d=1 and d=2.
