Properties of a multichannel resonant-level model

Technical Report:

Abstract

By use of Tomonaga-Luttinger bosonization we find that a multichannel resonant-level model can be transformed into a single-channel Kondo model with antiferro- or ferromagnetic interaction depending on the parameter {gamma} given in terms of the phase shifts. The specific heat and the dynamics of the local impurity have been studied which show a Fermi-liquid vs non-Fermi-liquid transition at {gamma}{sub c} = 1. (author). 19 refs.
