INSTABILITIES OF THE ABRIKOSOV-SUHL RESONANCE

We consider the possibility that instabilities of the Abrikosov-Suhl r esonance lead to new fixed-point behavior of the Kondo effect in a lat tice environment. In one scenario, a pairing component to the resonant scattering develops in the Kondo lattice, leading to an odd-frequency superconductor. We discuss experiments that can discriminate between this picture and d-wave pairing, and its relationship to the non-Fermi -liquid fixed point of the overscreened Kondo model.
