Abstract

We use simulations within the Migdal-Kadanoff approach to probe the scales relevant for rejuvenation and memory in Ising spin glasses. First we investigate scaling laws for domain wall free energies and extract the chaos overlap length [Formula presented]. Then we perform out of equilibrium simulations that follow experimental protocols. We find that (1) a rejuvenation signal arises at a length scale significantly smaller than [Formula presented], and (2) memory survives even if equilibration goes out to length scales larger than [Formula presented]. Theoretical justifications of these phenomena are then considered.
