Two-channel Kondo physics in odd impurity chains
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,...
