Second order virial expansion for an atomic gas in a harmonic waveguide

Résumé

The virial expansion for cold two-component Fermi and Bose atomic gases is considered in presence of a waveguide and in the vicinity of a Feshbach resonance. The interaction between atoms and the coupling with the Feshbach molecules is modeled by using a quantitative separable two-channel model. The scattering phase-shift in a atomic waveguide is defined. This permits to extend the Beth-Uhlenbeck formula for the second order virial coefficient to this inhomogeneous case.
