The anisotropic multichannel spin-$S$ Kondo model: Calculation of scales from a novel exact solution

Strongly Correlated Electrons 2009-11-10 v1

Abstract

A novel exact solution of the multichannel spin-SS Kondo model is presented, based on a lattice path integral approach of the single channel spin-1/2 case. The spin exchange between the localized moment and the host is of XXZXXZ-type, including the isotropic XXXXXX limit. The free energy is given by a finite set of non-linear integral equations, which allow for an accurate determination of high- and low-temperature scales.
