Curvature-induced long ranged supercurrents in diffusive SFS Josephson Junctions, with dynamic $0-\pi$ transition

Abstract

We report that spin supercurrents can be induced in diffusive SFS Josephson junctions without any magnetic misalignment or intrinsic spin orbit coupling. Instead, the pathway to spin triplet generation is provided via geometric curvature, and results in a long ranged Josephson effect. In addition, the curvature is shown to induce a dynamically tunable $0-\pi$ transition in the junction. We provide the analytic framework and discuss potential experimental and innovation implications.
