Activated dynamic scaling in disordered systems (invited)

The long time dynamics of various random systems is discussed in terms of a general activated dynamic scaling Ansatz. The natural dynamic scaling variable is (ln t)/ξψ where t is the time and ξ a correlation length. Applications include the critical behavior of random field Ising magnets, the ordered phase of spin glasses, and approach to equilibrium in the ordered phases of these and other random systems.
