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.

Liquid Model

The temperature dependence of Coulomb blockade peaks of a one dimensional quantum dot is calculated. The Coulomb interaction is treated microscopically using the Luttinger liquid model. The electron interaction is assumed to be non-homogeneous with a maximum strength near the quantum dot. The conductance peaks show non-analytic power law behaviour induced by the interaction. It is shown that there is a crossover in the power law which is related to the inhomogeneity of the interaction.
