Abstract

We study the charge transport and thermoelectric properties of the junction, comprising double quantum dot embedded in T-shaped geometry on the interface between two normal/ferromagnetic electrodes and superconducting lead. We show that the interdot coupling plays major role in controlling the local and nonlocal transport properties of this setup. For the weak interdot coupling limit, we obtain the interferometric (Fano-type) lineshapes imprinted in the quasiparticle spectra, conductances and Seebeck coefficients. In contrast, for the strong interdot coupling, we predict that the local and nonlocal transport coefficients are primarily dependent on the molecular Andreev bound states induced by superconducting proximity effect, simultaneously in both quantum dots.
