The universality class of absorbing phase transitions with a conserved field

arXiv:cond-mat/0004242 · doi:10.1103/PhysRevLett.85.1803

Abstract

We investigate the critical behavior of systems exhibiting a continuous absorbing phase transition in the presence of a conserved field coupled to the order parameter. The results obtained point out the existence of a new universality class of nonequilibrium phase transitions that characterizes a vast set of systems including conserved threshold transfer processes and stochastic sandpile models.
