Self-generated flux in Josephson junctions with alternating critical current density
We study an interesting state with a self-generated magnetic flux in a long Josephson junction. The critical current density j c is assumed to alternate randomly along the tunnel contact on a length scale much less than the local Josephson penetration depth. The phase difference is then a sum of an alternating term and a smooth term which self-consistently contribute to the formation of a stati...
متن کامل4p-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...
