P-wave contact tensor: Universal properties of axisymmetry-brokenp-wave Fermi gases

Abstract

We investigate universal properties of a p-wave Fermi gas with a resonant interaction in which the axisymmetry is broken spontaneously or externally. Here, the short-range correlations can be completely characterized by the nine-component p-wave contact tensor, which can be measured by applying a generalized adiabatic sweep theorem. The distinctive features of the p-wave contact tensor emerge in a normal p-wave Fermi gas in an anisotropic trap and in a superfluid phase. An experimental scheme to measure the p-wave contact tensor and test the adiabatic sweep theorem is also discussed.
