DOI: 10.1103/physrevb.100.104518
Abstract: Proximity induced superconducting states in the surface of magnetically doped topological insulators can host chiral Majorana modes. We consider a Josephson junction in that system with changing the chemical potential, which drives a topological phase… read more here.

DOI: 10.1109/tasc.2018.2796596
Abstract: We studied the modulation characteristics of the Josephson current through the Nb/Al–AlOx /Nb tunnel junction by applying an external magnetic field parallel to the junction plane two-dimensionally. We can obtain much information about uniformity in… read more here.
