Parity dependent Josephson current through a helical Luttinger liquid
We consider a superconductor–two dimensional topological insulator–superconductor junction and study how the 2 π - and 4 π -periodic Josephson currents are affected by the electron–electron interaction. In the long-junction limit the supercurrent can be evaluated by modeling the system as a helical...
