We report on the creation of homogeneous Fermi gases of ultracold atoms in a uniform box potential. For the ideal Fermi gas, the momentum distribution directly reveals Pauli blocking in momentum space and the formation of the Fermi surface. Spatially uniform pair condensates are observed in a spin-balanced mixture with resonant interactions. To combine the advantages of harmonic and uniform potentials, we introduce a hybrid trap for high signal-to-noise local density measurements. Using this novel geometry, the temperature and isothermal compressibility of spin-polarized and spin-balanced unitary Fermi gases are extracted.
In addition, we present preliminary results on tomographic RF spectroscopy of unitary Fermi gases and thermodynamic properties of polarons.
