The relation between Parisi scheme and multi-thermalized dynamics in finite dimensions

In this note we summarize the connections between equilibrium and slow out of equilibrium dynamics in finite dimensional glasses, such as we understand them today. If we assume that a finite-dimensional system is stable with respect to a family of weak random perturbations (stochastic stability), then its dynamics have a `Multithermalization’ structure if and only if the Boltzmann-Gibbs distribution obeys an Ultrametric Parisi distribution.
