Abstract
We consider the operator product expansions for unitarity fermions. We compute the dynamic structure factor at large frequency and wave number away from the one-particle peak. The overall normalization of is determined by Tan’s contact parameter, and the dependence on and is obtained in closed analytic form. We also find energy deposited into the system by small, rapid variations of the inverse scattering length.
