主  持  人：严忠波教授

报告摘要：Topological superconductors have garnered significant attention in recent years due to due to their capacity to harbor exotic quasiparticle excitations, particularly Majorana zero modes. However, naturally occurring topological superconductors are rare, limiting their study and potential applications. In this talk, I am going to talk about our recent research on engineering and controlling chiral and helical topological superconductivity in two-dimensional systems. I will demonstrate how these unique superconducting states can be created and manipulated by leveraging the interplay between spin-orbit coupling and various other phenomena, including charge ordering, magnetism, and light-matter interaction.
