Towards local probing of ultracold Fermi gases — •Jonas Siegl, Kai Morgener, Wolf Weimer, Klaus Hueck und Henning Moritz — Institut für Laserphysik, Universität Hamburg Luruper Chaussee 149, 22761 Hamburg

Ultracold fermionic gases are an ideal model system for the study of quantum many-body phenomena. Of particular interest are two-dimensional strongly correlated systems which can exhibit superfluidity and Berezinskii-Kosterlitz-Thouless-type transitions.

Here we present our new experimental setup aimed at studying two-dimensional strongly interacting Fermi gases. Lithium atoms are laser-cooled and transferred into a resonator enhanced dipole trap. Due to the large volume and depth of this resonator trap, we achieve transfer efficiencies of up to 50%. For final evaporative cooling to quantum degeneracy, we transfer the atoms into a running wave dipole trap.

The atoms will be studied and controlled with a high resolution imaging system for which we have achieved a resolution of 660nm. The current status of the experiment will be presented.
