报告介绍 Abstract：　　Realization of long-range magnetic order in two-dimensional (2D) van der Waals magnets facilitates exploitation of exotic emergent magnetic properties in reduced dimensionality. Here we report our recent progresses surrounding rich topological properties of 2D magnets via element mutation. Starting with the parental 2D ferromagnet CrI3, we first show that proper mutation of Cr with nei...

报告介绍 Abstract：　　The topological states of matter and topological materials have been attracting extensive interests as one of the frontier topics in condensed matter physics and materials science since the discovery of quantum Hall effect in 1980s.

报告介绍 Abstract:　　Spin-orbit coupling plays an important role in condensed matter physics. It is conventionally viewed as a single-electron property inherited from the Dirac equation but not directly related to many-body interactions. In this talk, we propose a conceptually new mechanism for the spontaneous generation of spin-orbit coupling from unconventional type of magnetic phase transitions (e.g. p-w...

报告介绍 Abstract：　　We study the Josephson effect in the multiterminal junction of topological superconductors. We use the symmetry-constrained scattering matrix approach to derive band dispersions of emergent subgap Andreev bound states in the parameter space of superconducting phase differences. We find distinct topologically protected band crossings that serve as monopoles of finite Berry curvature. Pa...
