An apparatus for ultracold Fermi gases using sodium and lithium — •Jens Appmeier, Marc Repp, Stefan Weis, Anton Piccardo-Selg, Jan Krieger, Elisabeth Brama, Peter Krüger, and Markus K. Oberthaler — Kirchhoff-Institut für Physik, Heidelberg

We report on the setup of an apparatus for cooling fermionic ⁶Li atoms to quantum degeneracy. As a refrigerant for the fermions, ²³Na is used and standard cooling schemes are applied. By tuning the interatomic interactions of ⁶Li via Feshbach resonances it is possible to study the BEC-BCS crossover. We intend to study this regime in lower dimensions by making use of optical lattices. The current progress of the experimental setup will be reported.
