We investigate the jump motion among potential energy minima of aLennard-Jones model glass former by extensive computer simulation. From thetime series of minima energies, it becomes clear that the energy landscape isorganized in superstructures, called metabasins. We show that diffusion can bepictured as a random walk among metabasins, and that the whole temperaturedependence resides in the distribution of waiting times. The waiting timedistribution exhibits algebraic decays: $\tau^{-1/2}$ for very short times and$\tau^{-\alpha}$ for longer times, where $\alpha\approx2$ near $T_c$. Wedemonstrate that solely the waiting times in the very stable basins account forthe temperature dependence of the diffusion constant.Comment: to be published in Phys. Rev.
