Stochastic Lattice Models with Several Absorbing States

arXiv:cond-mat/9608065 · doi:10.1103/PhysRevE.55.219

Abstract

We study two models with n equivalent absorbing states that generalize the Domany-Kinzel cellular automaton and the contact process. Numerical investigations show that for n=2 both models belong to the same universality class as branching annihilating walks with an even number of offspring. Unlike previously known models, these models have no explicit parity conservation law.
