Effects of interactions in transport through Aharonov-Bohm-Casher interferometers

Abstract

We study the conductance through a ring described by the Hubbard model (such as an array of quantum dots), threaded by a magnetic flux and subject to Rashba spin-orbit coupling (SOC). We develop a formalism that is able to describe the interference effects as well as the Kondo effect when the number of electrons in the ring is odd. In the Kondo regime, the SOC reduces the conductance from the unitary limit, and in combination with the magnetic flux, the device acts as a spin polarizer.
