Two-channel Kondo physics in odd impurity chains

Abstract:

We study odd-membered chains of spin-12 impurities, with each end connected to its own metallic lead. For antiferromagnetic exchange coupling, universal two-channel Kondo (2CK) physics is shown to arise at low energies. Two overscreening mechanisms are found to occur depending on coupling strength, with distinct signatures in physical properties. For strong interimpurity coupling, a residual chain spin-12 moment experiences a renormalized effective coupling to the leads, while in the weak-cou...
