DESCRIPTION:Speaker: Lennart Dabelow\nhosted by Laszlo Erdös\nAbstract: Un
 derstanding the macroscopically observable behavior of large complex syste
 ms based on the laws governing their microscopic constituents is an intrig
 uing fundamental problem. Traditional statistical mechanics introduces "en
 sembles" (e.g.\, microcanonical\, canonical\, ...) to describe many-body s
 ystems at equilibrium. The success of this method relies on the empirical 
 fact that many microscopically distinct systems or states exhibit the same
  macroscopic properties. We first review how this cornerstone of equilibri
 um thermodynamics can be understood within a quantum mechanical framework.
  Thereafter\, we sketch recent ideas to develop a similar ensemble approac
 h for systems and processes away from equilibrium. Adopting this approach\
 , we present specific examples of analytical predictions for the observabl
 e dynamics of many-body quantum systems and verify them by comparison with
  experiments and numerical simulations.
