Nonequilibrium Kondo problem with spin-dependent chemical potentials: Exact results

Abstract

We give a brief review of the Kondo effect and exactly solve the nonequilibrium Kondo problem at the special point in the parameter space of the model with spin-dependent chemical potentials. Using the obtained solution, we compute several experimentally observable quantities: charge current, spin current and magnetic properties. Applications to the physically important cases such as the case where the impurity spin is placed in between two ferromagnetically polarized leads are discussed.
