Condensed Matter Seminar: Dynamical Glass
Sergej Flach, Center for Theoretical Physics of Complex Systems, Daejeon, South Korea
Abstract:
Classical many body interacting systems are typically chaotic and their microcanonical dynamics ensures that time averages and phase space averages are identical. In proximity to an integrable limit the properties of the network of nonintegrable action space perturbations will decide whether ergodicity will hold arbitrarily close to the limit (albeit with diverging relaxation times), or whether the system fragments into regular and chaotic parts and enters a nonergodic dynamical glass phase at a finite distance to the integrable limit.
