Non-equilibrium relaxation and critical aging for driven Ising lattice
gases
   [PDF]

George L. Daquila, Uwe C. Tauber
We employ Monte Carlo simulations to study the non-equilibrium relaxation of
driven Ising lattice gases in two dimensions. Whereas the temporal scaling of
the density auto-correlation function in the non-equilibrium 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 auto-correlations
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.
