­­P-wave Efimov physics creates a universal trimer in three fermion systems

Efimov physics at the p-wave unitary limit for three equal mass fermions interacting via Lennard-Jones potentials is predicted to modify the long-range interaction potential energy in multiple symmetries, but without producing a true Efimov effect. This analysis treats the orbital angular momenta and parities, $L^{\Pi} = 0^{+}, 1^{+}, 1^{-}, and 2^{-}$, for either three spin-polarized fermions or two spin-up and one spin-down fermion. Our results for the long-range interaction predicts that either one or two novel p-wave unitary channels emerge at unitarity, in multiple scenarios where the two-body p-wave scattering volume diverges for either a single-component or a two-component fermionic trimer. The new type of p-wave universal trimer can be formed in some specific symmetries i.e. $L^{\Pi} = 1^{+} or 1^{-}$.
