Speckle Imaging of Spin Fluctuations in a Strongly Interacting Fermi Gas

Spin fluctuations and density fluctuations are studied for a two-component gas of strongly interacting fermions along the BEC-BCS crossover [1].  Spin fluctuations are observed by directly measuring the difference in densities for the two spin states.  This was done by using a probe laser which had equal detuning from both states, but with opposite signs.

Spin gradient demagnetization cooling of ultracold atoms

We have demonstrated a new cooling method in which a time-varying magnetic field gradient is applied to an ultracold spin mixture [1].  We prepare a two-component cloud of rubidium atoms, either in the superfluid or Mott insulator phase, in a strong field gradient separating the two components with a narrow mixed region between the pure-spin...

Quantum degenerate Bose-Fermi mixture of chemically different atomic species with widely tunable interactions

We have created a quantum degenerate Bose-Fermi mixture of 23Na and 40K with widely tunable interactions via broad interspecies Feshbach resonances. Twenty Feshbach resonances between 23Na and 40K were identified. The large and negative triplet background scattering length between 23Na and 40K causes a sharp enhancement of the fermion density in the presence of a...
