Measurement of $p$-wave contacts in an ultracold Fermi gas of ${}^6$Li atoms

Abstract

Using radio-frequency (RF) spectroscopy, we measure the $p$-wave contacts in a Fermi gas of ${}^6$Li atoms near the $p$-wave Feshbach resonance. The RF spectrum exhibits clear asymptotic behavior, characterized by ${\tilde{\omega }}^{-1/2}$ and ${\tilde{\omega }}^{-3/2}$ dependencies. The magnetic-field dependence of the $p$-wave contacts agrees reasonably well with the virial expansion theory in a detuned magnetic field range, validating the theory near the Fermi temperature. The $p$-wave contacts measured in this study constitute a second dataset, complementing the data obtained from the ${}^{40}$K system and contributing valuable insights into $p$-wave interactions in ultracold Fermi gases.
