Subgap states and quantum phase transitions in one-dimensional superconductor–ferromagnetic insulator heterostructures
Subgap states and quantum phase transitions in one-dimensional superconductor–ferromagnetic insulator heterostructures
We theoretically study the spectral properties of a one dimensional semiconductor-superconductor-ferromagnetic insulator (SE-SU-FMI) hybrid nanostructure, motivated by recents experiments where such devices have been fabricated using epitaxial growing techniques. We model the hybrid structure as a one-dimensional single-channel semiconductor nanowire under the simultaneous effect of two proximity-induced interactions: superconducting pairing …
