Persistence of translational symmetry in the BCS model with radial pair interaction
arXiv:1612.03303 · doi:10.1007/s00023-018-0665-7
Abstract
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 critical temperature. In the case of vanishing angular momentum our results carry over to the three-dimensional case.
