Enhancement of pairing due to the presence of resonant cavities
arXiv:cond-mat/0506560 · doi:10.1103/PhysRevB.72.174504
Abstract
A correlated fermion system is considered surrounding a finite cavity with virtual levels. 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.
