Interplay between Yu-Shiba-Rusinov states and multiple Andreev reflections
Interplay between Yu-Shiba-Rusinov states and multiple Andreev reflections
Motivated by recent scanning tunneling microscopy experiments on single magnetic impurities on superconducting surfaces, we present here a comprehensive theoretical study of the interplay between Yu-Shiba-Rusinov bound states and (multiple) Andreev reflections. Our theory is based on a combination of an Anderson model with broken spin degeneracy and nonequilibrium Green's …
