Discontinuous transitions can survive to quenched disorder in a 2-dimensional nonequilibrium system

We explore the effects that quenched disorder has on discontinuous nonequilibrium phase transitions into absorbing states. We focus our analysis on the Naming Game model, a nonequilibrium low-dimensional system with different absorbing states. Based on the results of the finite-size scaling analysis and on the temporal dynamics of the density of active sites near the transition point we can show that spatial quenched disorder does not destroy the discontinuous transition.
