Single-particle spectroscopies of p-wave and d-wave interacting Bose gases in normal phase

Abstract

Motivated by experiments of interacting quantum gases across high partial wave resonance, we investigated the thermodynamic properties as well as single particle spectrums of Bose gases in normal phase for different interaction strengths both for p-wave and d-wave interactions. The equation of state, contact density, momentum distributions, and self-energies of single particle Green’s functions are
obtained in the spirit of ladder diagram approximations. Radio frequency (RF) spectrum, as an important experimental approach to detect Feshbach molecules or interaction effect, is calculated at different temperatures. A reversed temperature dependence on the BEC side and BCS side is identified for both p-wave and d-wave interactions. An estimation for the signal of RF spectra under typical experimental conditions is also provided.
