Salle de séminaire du groupe de Physique Statistique
In recent years an approach ("typicality") to thermodynamical relaxation that does not rely on projection methods has attracted considerable attention. It is based on the the idea that, in some sense, Hilbert space is "filled" with pure states each of which already individually features equilibrium ensemble properties. Thus relaxation simply appears as the venturing of a pure state into and through this class of states. The approach has been discussed for compound as well as for single system scenarios. We present both and comment on dynamics and the relation to projection methods.
