Anomalous Josephson effect in planar noncentrosymmetric superconducting devices

How can electrons tunneling through a superconductor--normal metal--superconductor junction create an anomalous Josephson effect? The authors posed this question to Dall-E 2, new open source artificial intelligence (AI) system, and got image result depicting quantum process. Remarkably AI art matches almost verbatim the actual Feynman diagram that captures physics of phenomenon. In work, calculate these diagrams, analyze current in planar double-barrier configurations hybrid circuits. They use paradigmatic Rashba model spin-orbit coupling describe noncentrosymmetric normal region junction.
