abstract
We review recent theoretical progress on glassy dynamics, with special emphasis on the importance and universality of the ``aging regime'', which is relevant to many experimental situations. The three main subjects which we address are: (i) Phenomenological models of aging (coarsening, trap models), (ii) Analytical results for the low-temperature dynamics of mean-field models (corresponding to the mode-coupling equations); and (iii) Simple non-disordered models with glassy dynamics. We discuss the interrelation between these approaches, and also with previous work in the field. Several open problems are underlined -- in particular the precise relation between mean-field like (or mode-coupling) descriptions and finite dimensional problems.

Activated dynamics in the quantum random field Ising model
NP-FRG computation shows the quantum RFIM has activated dynamics ln τ ~ ξ^Ψ at T=0, with Ψ set by classical RFIM static exponents and bare kernel exponent σ, crossing over to thermal activation at finite T.
