BCS-BEC Crossover and Pairing Fluctuations in a Two Band Superfluid/Superconductor: A <i>T</i> Matrix Approach
We investigate pairing fluctuation effects in a two band fermionic system, where a shallow band in the Bardeen−Cooper−Schrieffer−Bose−Einstein condensation (BCS-BEC) crossover regime is coupled with a weakly interacting deep band. Within a diagrammatic <i&g...
