Persistence of translational symmetry in the BCS model with radial pair interaction
Andreas Deuchert, Alissa Geisinger, Christian Hainzl +1
We consider the two-dimensional BCS functional with a radial pair interaction. We show that the translational symmetry is not broken in a certain temperature interval below the cri…

General pairing mechanisms in the BCS-theory of superconductivity
C. Hainzl, M. Loss
Starting from the linearized BdG-equation we make the simple observation that pairing can occur between particles with total momenta different from zero, e.g., with equal momentum…
