Kondo effect in a Luttinger liquid: A two-channel Kondo fixed point is not possible

Karyn Le Hur

Research output: Contribution to journal › Article › peer-review

Abstract

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 ≠ 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.
