Resumen:
We study the conductance through a ring described by the Hubbard model (such as an array of quantumdots), threaded by a magnetic flux and subject to Rashba spin-orbit coupling (SOC). We develop aformalism that is able to describe the interference effects as well as the Kondo effect when the number ofelectrons 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.
