Spin Glasses

This thesis addresses the surprising features of zero-temperature statics and dynamics of several spin glass models, including correlations between soft spins that arise spontaneously during avalanches, and the discovery of localized states that involve the presence of two-level systems.

Aceasta teza abordeaza caracteristicile surprinzatoare ale staticii de temperatura zero si dinamica mai multor modele de sticla rotativa, inclusiv corelatiile dintre rotirile moi care apar spontan in timpul avalanselor si descoperirea starilor localizate care implica prezenta sistemelor pe doua niveluri.
