TL;DR
This paper investigates the nonequilibrium dynamics of the Ising Spin Glass over a vast timescale, introducing new analysis methods and providing evidence for key theoretical features, suggesting non-coarsening behavior.
Contribution
The study introduces novel, model-independent techniques to analyze spin glass dynamics and provides strong evidence for theoretical concepts like the replicon correlator and overlap equivalence.
Findings
Evidence for a replicon correlator
Support for overlap equivalence
Indications of non-coarsening behavior
Abstract
We study numerically the nonequilibrium dynamics of the Ising Spin Glass, for a time that spans eleven orders of magnitude, thus approaching the experimentally relevant scale (i.e. {\em seconds}). We introduce novel analysis techniques that allow to compute the coherence length in a model-independent way. Besides, we present strong evidence for a replicon correlator and for overlap equivalence. The emerging picture is compatible with non-coarsening behavior.
