  author={Shuwai Leung and Yang Liu and Feifei Li and Cheng-Peng Liang and Yin Poo and Jian‐Hua Jiang},
Topological phases of matter are featured with exotic edge states. However, the fractional quantum numbers at edges, though predicted long ago by Jackiw and Rebbi, remain elusive in topological photonic systems. Here, we report on the observation of fractional quantum numbers at the topological edges and corners in oneand two-dimensional photonic crystals. The fractional quantum numbers are determined via the measurements of the photonic local density-of-states. In one-dimensional photonic…

Energy density as a probe of band representations in photonic crystals

Topological quantum chemistry (TQC) has recently emerged as an instrumental tool to characterize the topological nature of both fermionic and bosonic band structures. TQC is based on the study of

Bulk-disclination correspondence in topological crystalline insulators.

It is shown that both the fractional charge and the localized states emerge at the disclination in the TCI phase but vanish in the trivial phase, revealing a fundamental phenomenon and a paradigm for exploring topological materials.

Trapped fractional charges at bulk defects in topological insulators.

It is experimentally demonstrated that disclination defects can robustly trap fractional charges in TCI metamaterials, and shown that this trapped charge can indicate non-trivial, higher-order crystalline topology even in the absence of any spectral signatures.
