Absorbing phase transitions of branching-annihilating random walks.

چکیده
The phase transitions to absorbing states of the branching-annihilating reaction-diffusion processes mA-->(m+k)A, nA-->(n-l)A are studied systematically in one space dimension within a new family of models. Four universality classes of nontrivial critical behavior are found. This provides, in particular, the first evidence of universal scaling laws for pair and triplet processes.

Two-Species Branching Annihilating Random Walks with One Offspring
The last decades have seen considerable efforts to understand nonequilibrium absorbing phase transitions from an active phase into an absorbing phase consisting of absorbing states [1]. Once the system is trapped into an absorbing state, it can never escape from the state. Various one dimensional lattice models exhibiting absorbing transitions have been studied, and most of them turn out to bel...
متن کاملUniversality Class of Two-Offspring Branching Annihilating Random Walks
We analyze a two-offspring Branching Annihilating Random Walk (n = 2 BAW) model, with finite annihilation rate. The finite annihilation rate allows for a dynamical phase transition between a vacuum, absorbing state and a non-empty, active steady state. We find numerically that this transition belongs to the same universality class as BAW’s with an even number of offspring, n ≥ 4, and that of ot...
متن کاملReentrant phase diagram of branching annihilating random walks with one and two offspring.
We investigate the phase diagram of branching annihilating random walks with one and two offsprings in one dimension. A walker can hop to a nearest neighbor site or branch with one or two offsprings with relative ratio. Two walkers annihilate immediately when they meet. In general, this model exhibits a continuous phase transition from an active state into the absorbing state (vacuum) at a fini...
متن کاملReaction-diffusion processes and non-perturbative renormalisation group
This paper is devoted to investigating non-equilibrium phase transitions to an absorbing state, which are generically encountered in reactiondiffusion processes. It is a review, based on [1, 2, 3], of recent progress in this field that has been allowed by a non-perturbative renormalisation group approach. We mainly focus on branching and annihilating random walks and show that their critical pr...
متن کاملBranching annihilating random walks with parity conservation on a square lattice
Using Monte Carlo simulations we have studied the transition from an “active” steady state to an absorbing “inactive” state for two versions of the branching annihilating random walks with parity conservation on a square lattice. In the first model the randomly walking particles annihilate when they meet and the branching process creates two additional particles; in the second case we distingui...
