"High-Temperature Superfluidity in Ultra-Cold Fermi Gases"
An optically-trapped Fermi gas of 6Li atoms becomes strongly interacting when it is tuned to a Feshbach scattering resonance. Such a gas is predicted to be a very high temperature superfluid - the transition temperature is a large fraction of the Fermi energy. I will describe experimental evidence for superfluidity which arises in anisotropic expansion of the gas, in the heat capacity, and in collective damping. These cold Fermi gases provide desktop analogs of exotic, strongly-interacting fermions in nature, from high temperature superconductors and neutron stars to quark-gluon plasmas.
