On the BCS gap equation for superfluid fermionic gases

arXiv:1403.2563

Abstract

We present a rigorous derivation of the BCS gap equation for superfluid fermionic gases with point interactions. Our starting point is the BCS energy functional, whose minimizer we investigate in the limit when the range of the interaction potential goes to zero.
