Unconventional Josephson junctions with topological Kondo insulator weak links

Unconventional Josephson effect in hybrid superconductor-topological insulator devices.

We report on transport properties of Josephson junctions in hybrid superconducting-topological insulator devices, which show two striking departures from the common Josephson junction behavior: a characteristic energy that scales inversely with the width of the junction, and a low characteristic magnetic field for suppressing supercurrent. To explain these effects, we propose a phenomenological...
