摘要：
Using the nonequilibrium Keldysh Green function technique, the influence of intradot Coulomb interactions on conductance for a parallel-coupled triple quantum dot system is investigated. The conductance as a function of electron energy is numerically calculated. The combined effect of the intradot Coulomb interaction and the magnetic flux leads to an intricate conductance lineshape. Moreover, both the magnetic flux and the interdot coupling strength may modulate the Fano effect.
