Theory of Fano effects in an Aharonov-Bohm ring with a quantum dot

Using a realistic model of a quantum dot embedded in an Aharonov-Bohm ring with several current-carrying channels, we demonstrate phase persistence in the Fano and Aharonov-Bohm effects as has been observed in experiments. The phase persistence arises because most of states contributing to the Coulomb oscillation of the conductance are weakly coupled to ring states through a small number of sta...

Thermoelectric effect in an Aharonov-Bohm ring with an embedded quantum dot

Thermoelectric effect is studied in an Aharonov-Bohm interferometer with an embedded quantum dot (QD) in the Coulomb blockade regime. The electrical conductance, electron thermal conductance, thermopower, and thermoelectric figure-of-merit are calculated by using the Keldysh Green's function method. It is found that the figure-of-merit ZT of the QD ring may be quite high due to the Fano effect ...

Comment on "Kondo resonance in a mesoscopic ring coupled to a quantum dot: exact results for the Aharonov-Bohm-Casher effects".

We study the persistent currents induced by both the Aharonov-Bohm and Aharonov-Casher effects in a one-dimensional mesoscopic ring coupled to a sidebranch quantum dot at Kondo resonance. For privileged values of the Aharonov-Bohm-Casher fluxes, the problem can be mapped onto an integrable model, exactly solvable by a Bethe ansatz. In the case of a pure magnetic Aharonov-Bohm flux, we find that...
