TL;DR
This paper investigates how resonant cavities can enhance pairing in correlated fermion systems, proposing a resonance condition that could lead to increased pairing temperatures, with potential experimental implications.
Contribution
It generalizes the Gell-Mann and Goldberger formula to many-body systems and demonstrates the potential for pairing enhancement via cavity resonance effects.
Findings
Pairing temperature can be enhanced at specific resonance conditions.
The study extends theoretical tools to many-body systems with cavities.
Potential for experimental realization of cavity-induced pairing enhancement.
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.
