Critical behavior of an interacting catalysis model(New Developments in Statistical Physics Similarities in Diversities,YITP Workshop)

Abstract

We study a generalized monomer-monomer model with repulsive interactions between the same species. There exists a tricritical point at which a first-order and two continous transition lines merge. These continuous transitions belong to the Reggeon field theory (RFT) universality class. We also suggest a model with an inactive state of doubly degenerate absorbing states. Preliminary results indicate that this model exhibits a continuous transition of a new universality class other than the RFT type.
