Ising critical behavior of a non-Hamiltonian lattice system
Ising critical behavior of a non-Hamiltonian lattice system
We study steady states in d-dimensional lattice systems that evolve in time by a probabilistic majority rule, which corresponds to the zero-temperature limit of a system with conflicting dynamics. The rule satisfies detailed balance for d=1 but not for d>1. We find numerically nonequilibrium critical points of the Ising class …
