Spin Group Symmetry Criteria for Odd-parity Magnets
Xun-Jiang Luo, Jin-Xin Hu, Meng-Li Hu +1
Odd-parity magnets (OPMs) have recently emerged as a new magnetic class, but their general symmetry criteria remain elusive. In this Letter, we establish these criteria through a c…

Universal Boundary-Modes Localization from Quantum Metric Length
Xing-Lei Ma, Jin-Xin Hu, K. T. Law
The presence of localized boundary modes is an unambiguous hallmark of topological quantum matter. While these modes are typically protected by topological invariants such as the C…
