Robustness of Dynamic Spin-Orbit Driven Josephson Junctions

ORAL

Abstract

Planar Josephson junctions, through their unusual current-phase relations with nontrivial anharmonicity, can be switched into their active state without any external bias current[1] through the combined use of dynamic spin-orbit coupling[2] and the superconducting diode effect[3]. We examine the effects disorder has on the ability for JJ switching in a noisy environment.  We investigate the robustness of such phenomena for their potential use in emerging spintronic and superconducting electronic systems.
