Nonequilibrium critical behavior of a species coexistence model
arXiv:cond-mat/0604271 · doi:10.1140/epjb/e2006-00217-7
Abstract
A biologically motivated model for spatio-temporal coexistence of two competing species is studied by mean-field theory and numerical simulations. In d>1 dimensions the phase diagram displays an extended region where both species coexist, bounded by two second-order phase transition lines belonging to the directed percolation universality class. The two transition lines meet in a multicritical point, where a non-trivial critical behavior is observed.
