Microscopy of a molecular 6Li-BEC — •Jakob Meineke, Bruno Zimmermann, Torben Müller, Henning Moritz, and Tilman Esslinger — Instute for Quantum Electronics, Quantum Optics Group, ETH Zurich, Switzerland
We present first results obtained with our new experimental setup that will allow us to study an ultracold fermionic quantum gas in potentials that can be arbitrarily controlled to less than a micrometer. An ultracold gas of 6Li is prepared by first loading 5× 107 atoms from a MOT into a high-finesse standing wave resonator. About 3× 106 atoms are transferred into an single-beam optical dipole trap. By translating the focussing lens, the thermal atoms are transported to a region of high optical access. Direct evaporation close to a Feshbach resonance allows us to create a BEC of up to 2× 105 molecules. The quantum degenerate gas is sandwiched between two microscope objectives, which will enable us to create arbitrary potentials and to locally probe the strongly interacting system. The current state of the experiment will be presented.
