Log-Poisson statistics and full aging in glassy systems

We argue that Poisson statistics in logarithmic time provides an idealized description of non-equilibrium configurational rearrangements in aging glassy systems. The description puts stringent requirements on the geometry of the metastable attractors visited at age tw. Analytical implications for the residence time distributions as a function of tw and the correlation functions are derived. These are verified by extensive numerical studies of short-range Ising spin glasses.
