Spin-Orbit induced phase-shift in Bi2Se3 Josephson junctions

An anomalous phase shift in a topological insulator based Josephson junction is expected but never been observed. Here, Assouline et al. observe an anomalous phase shift in a Bi2Se3 based Josephson junction in presence of an in-plane magnetic field, opening opportunities for phase-controlled Josephs...

Description
Résumé:An anomalous phase shift in a topological insulator based Josephson junction is expected but never been observed. Here, Assouline et al. observe an anomalous phase shift in a Bi2Se3 based Josephson junction in presence of an in-plane magnetic field, opening opportunities for phase-controlled Josephson devices.
