Аннотация

The proximity effect taking place in a normal dot coupled to a bulk superconducting reservoir by a tunnel contact with large normal conductance was investigated. The Coloumb interaction in the dot was found to suppress the proximity minigap induced in normal parts of the system. It was also observed that the tunneling minigap interpolated between its proximity-induced value in the regime of weak Coloumb interaction to the Coloumb gap in the regime of strong interactions. A nonuniversal two-step structure of the tunneling density of states was predicted in the intermediate case.
