摘要: We study spectroscopic signatures of a monochromatic boson mode interacting with T-shape double quantum dot coupled between the metallic and superconducting leads. Focusing on weak interdot coupling, we find that proximity effect together bosonic are responsible for series Fano-type resonances appearing simultaneously at negative positive energies. investigate these interferometric features discuss their influence subgap Andreev conductance taking into account correlation effects driven by Coulomb repulsion.
