There are two different scattering processes that contribute to the effective interactions. In one process the low-frequency Kondo resonance dominates and the effective interaction between quasiparticles is favorable for p-wave Cooper pairing at small values of kFR. In the other process all frequencies contribute and the effective interaction is against p-wave pairing for small kFR. This latter interaction is antiferromagnetic in nature.en-USIn Copyrightphysics, condensed matterArticle - Refereedhttp://journals.aps.org/prb/abstract/10.1103/PhysRevB.35.4728https://doi.org/10.1103/PhysRevB.35.4728
