Dynamics of Ultra-cold Atoms in Optical Lattices — •Sandro Wimberger — Institut für Theoretische Physik, Universität Heidelberg

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. Experimental as well as theoretical results for two paradigm systems are reported: on (1) the interband transport in a tilted lattice, i.e. a realization of the famous Wannier-Stark problem, and (2) on the stability of the temporal evolution in kicked lattice potentials. General perspectives on future directions of our study of strongly correlated bosons in lattice structures conclude the talk.
