Zusammenfassung

Gapped excitation spectra of Andreev states in one- and two-dimensional normal systems in contacts with superconductors are analyzed in the presence of a parallel magnetic field. It is shown that in the ballistic regime there is a specific interplay between magnetic field spin splitting and the effect of a proximity-induced screening supercurrent which preserves time-reversal symmetry for certain ...
