Anderson model with spin-flip-associated tunneling

Abstract

The spin-flip-associated transport through a quantum dot based on the Anderson model in equilibrium and nonequilibrium situations is studied. It is found that electrons are scattered due to the spin-flip effect via the normal and the Kondo channels. Our results show that the conductance is suppressed due to the spin-flip effect, and the suppression due to the spin-flip scattering via the Kondo channel is stronger for temperatures below the Kondo temperature.
