Out-of-equilibrium dynamical fluctuations in glassy systems
Abstract
In this paper we extend the earlier treatment of out-of-equilibrium mesoscopic fluctuations
in glassy systems in several significant ways. First, via extensive simulations, we
demonstrate that models of glassy behavior without quenched disorder display scalings
of the probability of local two-time correlators that are qualitatively similar to
that of models with short-ranged quenched interactions. The key ingredient for such
scaling properties is shown to be the development of a criticallike dynamical correlation
length, and not other microscopic details. This robust data collapse may be described
in terms of a time-evolving "extreme value" distribution. We develop a theory to describe
both the form and evolution of these distributions based on a effective σ model approach.
