Abstract
We theoretically investigate the nonequilibrium density of states (DOS) of a Kondo dot weakly coupled to Luttinger liquid leads by using the equation-of-motion technique of non-equilibrium Green functions. The joint effects of large bias voltage and moderately strong intralead interactions results in nontrivial modifications of the Kondo peak in the DOS. The DOS exhibits a two-channel Kondo physics for moderately strong interaction in the leads at zero temperature.
