Absorbing Phase Transitions with Coupling to a Static Field and a Conservation Law
arXiv:cond-mat/0306039
Abstract
The coupling of branching-annihilating random walks to a static field with a local conservation law is shown to change the scaling properties of their phase transitions to absorbing states. In particular, we find that DP-class transitions give rise to a new universality class distinct from that characterizing the depinning of the so-called linear interface model.
