Mesoscopic features in the transport properties of a Kondo-correlated quantum dot in a magnetic field

Abstract

We study the transport behavior induced by a small bias voltage through a quantum dot connected to one-channel finite-size wires. We describe the quantum dot by the Hubbard-Kondo which is solved by means of a quantum Monte Carlo method. We investigate the effect of a magnetic field applied at the quantum dot in the Kondo regime. We identify changes in the behavior of mesoscopic oscillations introduced by the magnetic field that have an analogous behavior to those observed as a function of the temperature.
