Interactions of ultracold atoms in optical dipole traps — •R. Grimm¹, M. Hammes¹, D. Rychtarik¹, T. Weber¹, J. Herbig¹, H.–C. Nägerl¹, H. Moritz², S. Jochim², M. Mudrich², S. Kraft², K. Singer², A. Mosk², and M. Weidemüller² — ¹Institut für Experimentalphysik, Universität Innsbruck, Austria — ²MPI für Kernphysik, Heidelberg, Germany

Optical dipole traps operating with laser light very far from resonance constitute a unique environment to study interaction processes between ultracold atoms in the electronic ground state. We explore evaporative cooling of an atomic cesium gas towards a two–dimensional gas and Bose–Einstein condensation, spin–mixtures of fermionic lithium atoms in view of pairing effects, and even mixtures of two different atomic species.
