We measure the free energy of the whole sample with respect to the free energy of a reference state which allows us to define a BCS functional with boundary conditions at infinity. Our main result is a lower bound for this energy functional in terms of expressions that typically appear in Ginzburg-Landau functionals.\r\n"],"identifier":["https://research-explorer.ista.ac.at/record/912"],"source":["Deuchert A.
