摘要
The fixed point of the two-channel Kondo (TCK) model does not respect the vacuum of the backward Kondo scattering exchange. It proves rigorously that such a solution for the Kondo effect in a Luttinger liquid is forbidden while backscattering effects are prominent. When U not equal 0, a description of the fixed point in terms of a local Fermi-liquid is not completely satisfactory since the Wilson ratio is not universal. (C) 1999 Elsevier Science B.V.
