We study the universal relations and normal-phase thermodynamics of a two-component ultracold Fermi gas with coexisting $s$- and $p$-wave interactions. Due to the orthogonality of two-body wave functions of different scattering channels, the universal thermodynamic relations of the system appear to be direct summations of contributions from each partial-wave scattering channels. These universal relations are dictated by a set of contacts, which can be associated with either $s$- or $p$-wave…

### Universal relations and normal-state properties of a Fermi gas with laser-dressed mixed-partial-wave interactions

In a recent experiment [P. Peng, $et$ $al.$, Phys. Rev. A \textbf{97}, 012702 (2018)], it has been shown that the $p$-wave Feshbach resonance can be shifted toward the $s$-wave Feshbach resonance by

It is shown that in the collision integral the particle-hole symmetry can be recast into a form of collision symmetry amenable to semiclassical simulation, and the effect of the collision delay on the shear viscosity is demonstrated.
