Title: Unconventional Josephson Effects in Conventional Materials: Artefacts vs. Promising Signals
Room K223, Institut Néel
Abstract: Deviations from the classic “sinusoidal” Josephson effect may contain evidence for interesting mesoscopic physics related to ballistic transport, few mode supercurrents, spin-orbit interaction, triplet and topological superconductivity. I have been chasing these phenomena my entire career, but i want each discovery to be for real. So I pay a lot of attention to alternative explanations. I will tell you a hopefully engaging story of how I personally tried to find some of the exotic Josephson effects, some successfully while others turned out to be someting else.
