Event Details & Abstract: 

Ultracold atom experiments can include the ability to arbitrarily tune interatomic interactions, which allows for unprecedented access to the regime of strongly interacting physics.  The majority of cold atom experiments, however, are carried out in an atom trap that imprints an inhomogeneous density on the cloud of atoms.  Many phenomena, especially the signatures of phase transitions, are rendered invisible by this non-uniform density.  I present a novel imaging technique that allows us to probe a region of nearly homogeneous density within a larger, inhomogenenous cloud.  Using this technique, I present new results for strongly interacting fermionic atoms, including the first measurements of the occupied spectral function of a homogeneous Fermi gas with strong interactions and the first direct observation of ``textbook" momentum distribution of an ideal Fermi gas.
