AGING WITHOUT DISORDER ON LONG-TIME SCALES

We study the Metropolis dynamics of a simple spin system without disor der, which exhibits glassy dynamics at low temperatures. We use an imp lementation of the algorithm of Bortz, Kalos and Lebowitz [1]. This me thod turns out to be very efficient for the study of glassy systems, w hich get trapped in local minima on many different time scales. We fin d strong evidence of aging effects at low temperatures. We relate thes e effects to the distribution function of the trapping times of single configurations.
