Findings

Electron glasses exhibit characteristic slow relaxations and aging.

Theoretical models can explain periodic aging experiments.

Recent work advances understanding of glassy dynamics in electronic systems.

Abstract

Examples of glasses are abundant, yet it remains one of the phases of matter whose understanding is very elusive. In recent years, remarkable experiments have been performed on the dynamical aspects of glasses. Electron glasses offer a particularly good example of the 'trademarks' of glassy behavior, such as aging and slow relaxations. In this work we review the experimental literature on electron glasses, as well as the local mean-field theoretical framework put forward in recent years to understand some of these results. We also present novel theoretical results explaining the periodic aging experiment.
