Nonequilibrium Andreev bound states population in short superconducting junctions coupled to a resonator
Nonequilibrium Andreev bound states population in short superconducting junctions coupled to a resonator
Inspired by recent experiments, we study a short superconducting junction of length $L\ensuremath{\ll}\ensuremath{\xi}$ (coherence length) inserted in a dc-SQUID containing an ancillary Josephson tunnel junction. We evaluate the nonequilibrium occupation of the Andreev bound states (ABS) for the case of a conventional junction and a topological junction, with the latter …
