Energy landscape and overlap distribution of binary Lennard-Jones glasses

We study the distribution of overlaps of glassy minima: taking proper care of residual symmetries of the system. Ensembles of locally stable, low-lyin g glassy states are efficiently generated by rapid cooling from the liquid phase which has been equilibrated at a temperature T-run. Varying T-run, we observe a transition from a regime where a broad range of states are sampl ed to a regime where the system is almost always trapped in a metastable gl assy state. We do not observe any structure in the distribution of overlaps of glassy minima, but find only very weak correlations, comparable in size to those of two liquid configurations.
