Kondo effect in a Luttinger liquid: nonuniversality of the Wilson ratio
arXiv:cond-mat/9903373 · doi:10.1103/PhysRevB.59.R11637
Abstract
Using a precise coset Ising-Bose representation, we show how backscattering of electrons off a magnetic impurity destabilizes the two-channel Kondo fixed point and drives the system to a new fixed point, in agreement with previous results. In addition, we verify the scaling proposed by Furusaki and Nagaosa and prove that the other possible critical fixed point, namely the local Fermi liquid class, is not completely universal when backscattering is included because the Wilson ratio is not well-defined in the spinon basis.
