Temperature dependence of $p$-wave contacts in a harmonically trapped Fermi gas
Abstract
We study the dependence of the -wave contact on the Fermi temperature and reduced temperature based on the number of closed-channel molecules. From the anisotropic pattern of dissociated molecules, we resolve the narrow and dipolar splitting of the -wave Feshbach resonance in Li, enabling the independent determination of the contact for all three components. For each component, we identify a near-resonant scaling with , indicating the contribution of the normalized effective range . In addition, we show that the peak contacts observed near resonance increase as is lowered, a trend that is accurately captured by estimates based on the second-order virial expansion. Our results, together with estimates from the -wave virial expansion, provide a route toward a complete understanding of the thermodynamics of resonantly enhanced -wave Fermi gases.
