Direct measurement of acoustic spectral density and fractional topological charge
Hao Ge, Zi-Wei Long, Xiang-Yuan Xu +5
Local density-of-states (LDOS) is a fundamental spectral property that plays a central role in various physical phenomena such as wave-matter interactions. Here, we report on the d…
Topological phenomena at topological defects
Zhi-Kang Lin, Qiang Wang, Yang Liu +4
There are two prominent applications of the mathematical concept of topology to the physics of materials: band topology, which classifies different topological insulators and semim…
Observation of fractional topological numbers at photonic edges and corners
Chengpeng Liang, Yang Liu, Fei-Fei Li +3
Topological phases of matter are featured with exotic edge states. However, the fractional topological numbers at edges, though predicted long ago by Jackiw and Rebbi, remain elusi…
p-orbital disclination states in non-Euclidean geometries
Ying Chen, Yuhang Yin, Ze-Huan Zheng +5
Disclinations are ubiquitous lattice defects existing in almost all crystalline materials. In two-dimensional nanomaterials, disclinations lead to the warping and deformation of th…
