The analysis of the stationary points visited during the aging dynamics shows the existence of two distinct regimes: i) at short times, tt_c, the system mainly lies in basins pertaining to minima of slowly decreasing energy. The dynamics for t>t_c can be represented by a simple random walk on a network of minima with a jump probability proportional to the inverse of the waiting time.", "revisions": [ { "version": "v2", "updated": "2000-12-01T09:46:10.000Z" } ], "analyses": { "keywords": [ "aging dynamics", "simple glasses", "topological description", "stationary points", "jump probability proportional" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
