Abstract: In the four-dimensional Edwards–Anderson±Jspin glasses, we observe that the quenched energies distribution fromT=2.5are similar to those observed for the equilibrium states atT=1.0. We show that although these states appear close there are subtle differences which are only seen when we try to quench the system fromT=2.5for a longer number of Monte Carlo steps. TheT=2.5states do not evolve to those seen for the states quenched fromT=1.0. We try to identify regions responsible for the subtle differences.
