Probing Strongly Interacting Fermi Gases in Homogeneous Potentials

We have realized a homogeneous optical potential for quantum degenerate Fermionic atoms ($^6$Li), and characterized the flatness using in-situ tomography. This is an ideal testbed for a variety of bulk condensed matter systems. In addition, this trap can be converted to a hybrid potential, which is flat along two of the directions and harmonic along the third. This is an ideal trapping geometry to study the density response of a quantum gas to varying external potentials. Here we present our recent measurements on strongly interacting Fermions in homogeneous potentials.
