Homogeneous Fermi Gases in the BEC-BCS Crossover

Recently, the realization of homogeneous quantum gases has opened up exciting new playgrounds for studying complex quantum many-body problems. By directly producing gases with a uniform density, we can now avoid many issues associated with the spatial variation of the density of harmonically-trapped gases. We demonstrate the creation of a homogeneous degenerate gas of $^{6}\mathrm{Li}$ atoms trapped in a cylindrical light box created by a combination of axicons and digital micromirror devices. We will report the measurement of the \emph{in-situ} atomic momentum distributions of the uniform Fermi gas across BEC-BCS crossover, and the study of its expansion dynamics from the uniform box trap.
