Abstract: In superconductors breaking both time and inversion symmetries, the supercurrent diode effect arises. We self-consistently calculate the supercurrent diode effect from microscopic models of two- dimensional clean superconductors with spin-orbit coupling under external Zeeman fields, and show that the Edelstein effect is responsible for the supercurrent diode effect. In turn, the supercurrent diode effect may serve as a direct measurement of the Edelstein effect as its application.

About the speaker: Noah F. Q. Yuan got his PhD at the Hong Kong University of Science and Technology in 2017. After that he went to Massachusetts Institute of Technology as a Postdoc from 2017 to 2020. He becomes an Associate Professor at the Harbin Institute of Technology (Shenzhen) since 2021. His interests are mainly the theory of unconventional superconductivity, such as finite-momentum superconductivity, two-dimensional superconductivity and topological superconductivity.
