Abstract
The nonequilibrium steady state of three-state Potts model evolving un der combined Glauber dynamics at temperature beta(-1) and Kawasaki dyn amics at beta' = 0 is studied by Monte-Carlo simulations. As the excha nge rate p increases, the phase transition changes from second to firs t order. The critical exponents of second-order transition are indepen dent of p, and the critical properties for different p belong to the s ame universality class.
