Non-equilibrium correlations in the infinite range Ising spin glass.

We use Monte Carlo simulations to investigate the possibility of obtaining equilibrium values of quantities which relax slowly to equilibrium by studying the evolution of their non- equilibrium behavior. As an example we study the order parameter distribution P(q) for the infinite range Ising spin glass during the approach to equilibrium. This is evaluated both by computing the overlap between two initially uncorrelated copies of the system and from the correlation between the same set of spins at two different times.
