Padurariu, C. (author), Jonkcheere, T. (author), Melin, R. (author), Feinberg, D. (author), Martin, T. (author), Nazarov, Y.V. (author) We describe the proximity effect in a short disordered metallic junction between three superconducting leads. Andreev bound states in the multiterminal junction may cross the Fermi level. We reveal that for a quasicontinuous metallic density of states, crossings at the Fermi level manifest as a closing of the proximity-induced gap. We calculate...
