Abstract
We analyze the quantum interference effects appearing in the charge current through the double quantum dots coupled in T-shape configuration to an isotropic superconductor and metallic lead. Owing to the proximity effect the quantum dots inherit a pairing which has a profound influence on nonequilibrium charge transport, especially in the subgap regime |V|<Δ/|e|. We discuss under what conditions the Fano-type line shapes might appear in such Andreev conductance and consider a possible interplay with the strong correlation effects.
