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.
