Reentrant phase diagram of branching annihilating random walks with one and two offspring

Abstract: 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 finite hopping probability. We map out the phase diagram by Monte Carlo simulations which shows a reentrant phase transiti… Show more

“…A pair of adjacent vacancies is required for a dimer to adsorb, so a state with alternating sites occupied by monomers can be identified with an absorbing state. The PC class phase transition of the r A = r B = 0 infinite repulsive case has been investigated in (Hwang et al, 1998;Kim and Park, 1994;Kwon and Park, 1995;Park et al, 1995;Park and Park, 1995). As one can see the basic reactions are similar to those of the MM model (eq.…”

“…Pair annihilation is allowed only between identical particles (A i + A i → ∅). In the branching process, a particle A i creates two identical particles in its neighborhood (A i → A i + 2A j ), with rate σ for i = j and rate σ ′ /(N − 1) for i = j.For N = 1, this model exhibits an absorbing transition of directed Ising type (Z 2 symmetry) at finite branching rate [10][11][12][13]. The N species generalization imposes the permutation symmetry S N between species.…”
