Bragg spectroscopy of a strongly interacting Fermi gas
Abstract: Strongly interacting Fermi systems arise in a wide variety of settings ranging from condensed matter systems including superconductivity to quark matter to strongly interacting neutrons in neutron stars. In this talk we will describe the use of Bragg spectroscopy to study pair correlations in a strongly interacting Fermi gas of ultracold lithium-6 atoms across the BEC-BCS crossover and at unitarity where the system exhibits universal behaviour. Measurements of the static structure show that short-range pair correlations in the strongly interacting Fermi gas closely follow a simple universal law based on a single short-range parameter, the "contact", over a broad range of momenta, interaction strengths and over a broad temperature range at unitarity.
