4p-periodic Josephson supercurrent in HgTe-based topological Josephson junctions
The Josephson effect describes the generic appearance of a supercurrent in a weak link between two superconductors. Its exact physical nature deeply influences the properties of the supercurrent. In recent years, considerable efforts have focused on the coupling of superconductors to the surface states of a three-dimensional topological insulator. In such a material, an unconventional induced p...

متن کاملJosephson Effect in SFXSF Junctions
We investigate the Josephson effect in SFXSF junctions, where SF is a superconducting material with a ferromagnetic exchange field, and X is a weak link. The critical current Ic increases with the (antiparallel) exchange fields, if the distribution of transmission eigenvalues of the X layer has its maximum weight at small values. This exchange-field enhancement of the supercurrent does not exis...
