Approaching a three-component Fermi gas in an optical lattice — •Martin Ries1,2, Andre Wenz1,2, Philipp Simon1,2, Thomas Lompe1,2, Friedhelm Serwane1,2, Gerhard Zürn1,2, and Selim Jochim1,2 — 1Physikalisches Institut, Universität Heidelberg — 2Max-Planck-Institut für Kernphysik
We report on our progress towards the realization of a three-component Fermi gas of 6Li atoms in a two-dimensional optical lattice. A three-component Fermi gas with its approximate SU(3) symmetry can serve as a simplified model system for QCD problems. In free space, however, the gas is not stable due to a large three-body loss rate. This issue can be overcome with the help of a lattice potential, which is predicted to block three-body losses and thus to stabilize the system.
We have set up a magneto-optical trap, from which precooled atoms will be transferred to an optical dipole trap and evaporatively be cooled to degeneracy. They will then be transferred into a two-dimensional optical lattice.
