Many-body dynamics in open quantum systems

Sandro Wimberger (Universite de Heidelberg)

par Bertrand Georgeot - 13 novembre 2012

Modern quantum and atom-optical experiments allow for an unprecedented control of microscopic degrees of freedom, not just in the initialization but also in the dynamical evolution of quantum states. This talk focuses on the dynamics of ultra-cold bosons in optical lattice structures. As two paradigms, we report on (1) experimental as well as theoretical results on the interband transport in a tilted lattice, i.e., a realization of the famous Wannier-Stark problem, and on (2) the many-body dynamics of atoms in dissipative leaky lattices. General perspectives on future directions of our study of strongly correlated bosons in lattice structures conclude the talk.
