报告摘要

Recently, superconducting diodes are becoming one of the hot topics in the study of superconductivity. In this talk I will talk about two types of superconducting diode effects, namely the supercurrent diode effect in one superconductor and the Josephson diode effect between two superconductors, whose properties are analyzed according to symmetry principles. Material candidates and examples are also discussed.
