Isotope effects in multiband superconductors
N. Kristoffel, P. Rubin
Isotope effects in a multiband superconductor with a leading interband pairing channel are investigated. A relatively small electron-phonon contribution into the pair-transfer inte…

Two-component scenario and related gaps in cuprates
N. Kristoffel, P. Rubin
A simple model of cuprate superconductivity with an electron spectrum prepared by doping is developed. The pair-transfer interaction couples the itinerant band with two components…
