Theory of a single magnetic impurity on a thin metal film in proximity to a superconductor

J Ortuzar, JI Pascual, FS Bergeret, MA Cazalilla - Physical Review B, 2023 - APS
We argue that the formation of Yu-Shiba-Rusinov excitations in proximitized thin films is
largely mediated by a type of Andreev-bound state named after de Gennes and Saint …
