Dynamics of a Fermi Gas in a Periodic Potential — •Herwig Ott, Estefania de Mirandes, Francesca Ferlaino, Giacomo Roati, Giovanni Modugno, and Massimo Inguscio — LENS and Dipartimento di Fisica, Università di

We study the dynamics of fermions and that of mixtures of fermions and bosons in a 1D optical lattice. By exciting the dipolar oscillation we find a damping of the center of mass motion and a localization of the cloud on one side of the potential. The role of collisions in this damping and localization process is investigated and reveals interesting phenomena like a collisionally induced transport. The current state of the experiment is reported.
