Kondo effect in Aharonov-Casher interferometer

We consider a model describing a spin field-effect transistor based on a quantum nano-wire with tunable spin-orbit interaction embedded between two ferromagnetic leads with anti-collinear magnetization. We investigate a regime of strong interplay between resonance Kondo scattering and interference associated with Aharonov-Casher effect. Using Keldysh technique at weak coupling regime we calculate perturbatively the charge current. It is predicted that the effects of spin-orbit interaction result in a non-vanishing current for any spin polarization of the leads including the case of fully polarized anti-collinear contacts. We analyze the influence of the Aharonov-Casher phase and degree of spin polarization in the leads onto a Kondo temperature.
