Relativistic corrections to the Cooperon mass: BCS versus BEC picture

Publication at Faculty of Mathematics and Physics |

Abstract

Relativistic corrections to the Cooperon mass are discussed for preformed Cooper pairs that become superconductive via the Bose-Einstein condensation (BEC) and for Cooperons in the Bardeen-Copper-Schrieffer (BCS) condensate. The distinction explains experimental results of Tate et al. (1989).
