摘要: We numerically investigate the aging dynamics of a monatomic Lennard-Jones glass, focusing on topology potential energy landscape which, to this aim, has been partitioned in basins attraction stationary points (saddles and minima). The analysis visited during shows existence two distinct regimes: (i) at short times system visits saddles whose energies orders decrease with t ; (ii) long mainly lies pertaining minima slowly decreasing energy. time can be represented by simple random walk network jump probability proportional inverse waiting time.
