A strongly interacting high partial wave Bose gas

Abstract

Motivated by recent experimental progress, we make an investigation of p- and d-wave resonant Bose gas. An explantation of the Nozieres and Schmitt-Rink (NSR) scheme in terms of two-channel model is provided. Different from the s-wave case, high partial wave interaction supports a quasi-bound state in the weak coupling regime. Within the NSR approximation, we study the equation of state, critical temperature and particle population distributions. We clarify the effect of the quasi-bound state on the phase diagram and the dimer production. A multi-critical point where normal phase, atomic superfluid phase and molecular superfluid phase meet is predicted within the phase diagram. We also show the occurrence of a resonant conversion between solitary atoms and dimers when temperature kBT approximates the quasi-bound energy.
