Revisiting the Toulouse limit of a Kondo junction

Following the development of a scheme to bosonize and debosonize consistently [1,2], we present in detail the Toulouse-point analytic solution of the two-lead (nonequilibrium) Kondo junction model. The existence and location of the solvable point is not modified, but the calculational methodology and the final expressions for observable quantities change markedly as compared to the previously accepted results. \\ \vskip 1mm \noindent [1] See arXiv:1508.03078 and arXiv:1508.03079 \\ \noindent [2] See also N.~Shah, invited talk
