报告题目 (Title):拓扑物理:从“体边对应”到“体缺陷对应”

报告人 (Speaker):蒋建华 教授(中国科学技术大学)

报告时间 (Time):2024年5月17日(周五)10:00

报告地点 (Place):校本部 G601

邀请人 (Inviter):刘俊杰 教授

主办部门:古天乐代言太阳集团物理系

报告摘要:

Topological phenomena have been a focus of physics and materials research where prominent effects emerge at systems’ edge boundaries via the celebrated bulk-edge correspondence. Recently, with designed metamaterials, novel topological phenomena have been revealed at defects, unveiling a paradigm of bulk-defect correspondence. In this talk, I show via several examples that defects, with their rich geometry, can induce unique topological effects that have never been seen before. I will also go over briefly other important findings in this direction and give an overview of potential future developments. Studies in this direction open a new research frontier in topological physics and materials science, with cutting-edge physics and unprecedented phenomena as well as potential applications.
