Abstract

Efimov physics at pp-wave unitarity for three equal mass fermions in multiple symmetries interacting via Lennard-Jones potentials is predicted to modify the long range interaction potential energy, but without producing a true Efimov effect. This analysis treats the following total orbital angular momenta and parities, JΠ=0+,1+,1J^{\Pi}=0^{+}, 1^{+}, 1^{-} and 22^{-}, for either three spin-polarized fermions (\uparrow \uparrow \uparrow ), or two spin-up and one spin-down fermion (\downarrow \uparrow \uparrow ). Our results for the long range interaction in some of those cases agree with previous work by Werner and Castin and by Blume {\it et al.}, namely in cases where the ss-wave scattering length goes to infinity. The present results extend those calculated interaction energies to small and intermediate hyperradii comparable to the van der Waals length, and we consider additional unitarity scenarios where the pp-wave scattering volume approaches infinity. The crucial role of the diagonal hyperradial adiabatic correction term is identified and characterized.
