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

30 Sep 2004 | Journal: | Eur. Phys. J. B 40 (2004) 25-42 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Abstract: | A novel exact solution of the multichannel spin-$S$ 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 $XXZ$-type, including the isotropic $XXX$ 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. | Source: | arXiv, cond-mat/0409755 | Services: | Forum | Review | PDF | Favorites |
