Transport through a strongly correlated quantum dot with Fano interference

We present transport properties of a strongly correlated quantum dot attached to two leads with a side coupled noninteracting quantum dot. Transport properties are analyzed using the slave boson mean field theory which is reliable in the zero temperature and low bias regime. It is found that the transport properties are determined by the interplay of two fundamental physical phenomena, i.e., the Kondo effects and the Fano interference. The linear conductance will depart from the unitary limit and the zero bias anomaly will be suppressed in the presence of interdot coupling. The zero bias shot noise Fano factor in mean field approximation varies with the interdot coupling and tends to the Poisson value. We find nonmonotonic increase of the shot noise Fano factor with the interdot coupling, which cannot be obtained within the noninteracting model.
