Structural Change of Cooper Pairs and Momentum-dependent Gap in Color Superconductivity

Abstract

dependence of the gap and to the spatial-structure of Cooper pairs. The gap at extremely high baryon density (∼ O(10ρ0) with ρ0 being the normal nuclear matter density) is shown to have a sharp peak near the Fermi surface due to the weak-coupling nature of QCD. On the other hand, the gap is a smooth function of the momentum at lower densities (∼ O(10ρ0… (More)
