Transmission probability through small interacting systems: application to a series of quantum dots

We apply the theory for the transmission probability View the MathML source through small interacting systems, which was formulated based on the Kubo formalism in the previous study, to a series of quantum dots described by the N-impurity Anderson model. Specifically, we calculate View the MathML source for N=2 with the order U2 self-energy and vertex corrections which satisfy the current conservation, and examine the two different parameter regions at t<Γ and t>Γ. Here t is the inter-dot transfer and Γ is the level broadening caused by the coupling with the noninteracting leads.
