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