Gate controlled anomalous phase shift in Al/InAs Josephson junctions [PDF]
Nature Communications, 2020 AbstractIn a standard Josephson junction the current is zero when the phase difference between superconducting leads is zero. This condition is protected by parity and time-reversal symmetries. However, the combined presence of spin–orbit coupling and magnetic field breaks these symmetries and can lead to a finite supercurrent even when the phase ...
