Abstract: | By applying the slave boson technique, we have studied the electron transport
through double-dot Aharonov-Bohm interferometer in the Kondo regime. For the system with symmetric
quantum dots, the linear conductance is shown to be enhanced by Kondo effect, but it is
suppressed in the deep dot level regime in the presence of
nonzero magnetic flux. The Aharonov-Bohm
oscillations of the conductance are also investigated. |
