The BCS energy gap at high density Henheik, Sven Joscha ; https://orcid.org/0000-0003-1106-327X Lauritsen, Asbjørn Bækgaard ; https://orcid.org/0000-0003-4476-2288 Mathematical Physics Statistical and Nonlinear Physics ddc:530 We study the BCS energy gap Ξ in the high–density limit and derive an asymptotic formula, which strongly depends on the strength of the interaction potential V on the Fermi surface. In combination with the recent result by one of us (Math. Phys. Anal. Geom. 25, 3, 2022) on the critical temperature Tc at high densities, we prove the universality of the ratio of the energy gap and the critical temperature.
