Abstract

We study theoretically the bound state spectrum and 0-pi transitions in ballistic quasi-one-dimensional superconductor/ferromagnetic insulator/superconductor Josephson junctions. In addition to the Andreev bound states, stemming from the phase coherence, the magnetic barrier gives rise to qualitatively different Yu-ShibaRusinov (YSR) bound states with genuine spectral features and spin ...
