Tunable Planar Josephson Junctions Driven by Time-Dependent Spin-Orbit Coupling
David Monroe, Mohammad Alidoust, Igor Žutić
Abstract
The Josephson effect has enabled many applications in superconducting electronics. Meanwhile, spin-orbit coupling (SOC) is crucial for many normal-state spin-based devices. Our respective advances in understanding these two phenomena have been largely decoupled, though, with the implications from their interplay left unexplored. The authors address this disconnect and discover fascinating opportunities in Josephson junctions that can be strongly tuned and dynamically driven by time-dependent SOC. Their transparent findings, supported by recent experiments, are directly related to superconducting electronics and spintronics, improving qubits, and controlling Majorana states.
