Title: Enhancement of fermion pairing due to the presence of resonant cavities

Abstract

A correlated fermion system surrounding a finite cavity with virtual levels is considered. The pairing properties are calculated and the influence of the cavity is demonstrated. To this end the Gell-Mann and Goldberger formula is generalized to many-body systems. We find a possible enhancement of pairing temperature if the Fermi momentum times the cavity radius fulfills a certain resonance condition, which suggests an experimental realization.
