Time-dependent phenomena in ultracold atoms confined by optical lattices — •Corinna Kollath — DPMC, University of Geneva, Quai Ernest-Ansermet 24, CH-1211 Geneva

The good tunability of the system parameters in the experimental realization of ultracold atoms in optical lattices opens the possibility to investigate time-dependent phenomena. We study the response of the ultracold atoms in the optical lattice to external time-dependent perturbations. We calculate the time-evolution of the perturbed system using the recently developed adaptive time-dependent DMRG (density-matrix renormalization group method).
