Abstract
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, a new open source artificial intelligence (AI) system, and got an image result depicting this quantum process. Remarkably this AI art matches almost verbatim the actual Feynman diagram that captures the physics of this phenomenon. In this work, the authors calculate these diagrams, and analyze anomalous Josephson current in the planar double-barrier configurations of hybrid circuits. They use the paradigmatic Rashba model of spin-orbit coupling to describe the noncentrosymmetric normal region of a junction.
