Universal Physics in Ultracold Fermi Gases

Ultracold gases of strongly interacting fermionic atoms can display universal properties which are independent of the interatomic potential. Several of these features, including Tan’s contact parameter, a universal relation for the static structure factor and the high momentum dynamic structure factor, can be investigated using Bragg spectroscopy. In this talk I will describe our experimental studies of these properties, the techniques used to probe both the spin and density responses of two-component Fermi gases and our progress towards a precision measurement of the homogeneous contact.
