Tuning Majorana zero modes with temperature in $\pi$-phase Josephson junctions

Umberto Borla, Dushko Kuzmanovski, Annica M. Black-Schaffer

We study a superconductor-normal state-superconductor (SNS) Josephson junction along the edge of a quantum spin Hall insulator (QSHI) with a superconducting $\pi$-phase across the ju…
