Superconducting junction with resonant tunneling

In oxide coating metals, localized states exist, which strongly hybridize with conduction electrons forming interface states (IS). This hybridization yields several qualitative and Quantitative new effects typical for oxide coated metals. The Hamiltonians for these new effects describe the: - enhanced coupling of IS to phonons, - strengthened and weakened superconducting interaction of IS, - additional - resonant - tunnel channels via IS.
