摘要
presented a novel exact solution of the multichannel spin- Kondo model, 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 -type, including the isotropic 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.
