DOI: 10.1103/PhysRevLett.108.1106020031-9007http://hdl.handle.net/10919/24488We employ Monte Carlo simulations to study the nonequilibrium relaxation of driven Ising lattice gases in two dimensions. Whereas the temporal scaling of the density autocorrelation function in the nonequilibrium steady state does not allow a precise measurement of the critical exponents, these can be accurately determined from the aging scaling of the two-time autocorrelations and the order parameter evolution following a quench to the critical point. We obtain excellent agreement with renormalization group predictions based on the standard Langevin representation of driven Ising lattice gases.application/pdfenIn Copyrightsize-scaling analysisphase-transitionsdiffusive systemscritical-behaviormonte-carlofield-theorymodelstatesPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevLett.108.110602https://doi.org/10.1103/PhysRevLett.108.110602
