Inelastic electron relaxation rates caused by Spin M/2 Kondo Impurities
arXiv:cond-mat/0305341 · doi:10.1103/PhysRevB.68.193301
Abstract
We study a spin S=M/2--Kondo system coupled to electrons in an arbitrary nonequilibrium situation above Kondo temperature. Coupling to hot electrons leads to an increased inverse lifetime of pseudo particles, related to the Korringa width. This in turn is responsible for the increased inelastic relaxation rates of the electronic system. The rates are related to spin--spin correlation functions which are determined using a projection operator formalism. The results generalize recent findings for S=1/2--Kondo impurities which have been used to describe energy relaxation experiments in disordered mesoscopic wires.
