Atom loss in a two-component Fermi gas near a Feshbach resonance

ORAL

Abstract

We present our recent progress on the study of the inelastic atom loss in a two-component ${ }^6Li$atoms near a Feshbach resonance at 834G. A degenerate${ }^6Li$atoms in the lowest two hyperfine states are prepared in an optical dipole trap after sympathetic cooling with bosonic ${ }^{23}Na$ atoms. The magnetic field is rapidly ramped up to a Feshbach resonance, and the inelastic atom loss is monitored. The rapid ramp-up of the magnetic fields offers the opportunity to study the non-equilibrium situation and the time-dependence of atom-atom correlations. We have tried to map out the atom loss in a cold Lithium gas as a function of magnetic field and the temperature. We present current experiments revealing the non-monotonic behavior which has been observed in preliminary experiments.
