Abstract

We study single component Fermi gas near a $p$-wave resonance with the lowest order constrained variational (LOCV) method. We obtain the energy per particle for the ground state of single component Fermi gas near a $p$-wave resonance with LOCV method. We also calculate compressibility of the single component Fermi gas near a $p$-wave resonance and it shows that near the $p$-wave resonance, the system would lose its stability and collapse. The two $p$-wave contacts are also obtained and their variation tendencies with interaction strength are consistent with recent experimental results.
