Edge State, Band Topology, and Time Boundary Effect in the Fine-Grained Categorization of Chern Insulators
H. C. Wu, H. S. Xu, L. C. Xie +1
We predict novel topological phases with broken time-reversal symmetry supporting the coexistence of opposite chiral edge states, which are fundamentally different from the photoni…

High-order spectral singularity
H. S. Xu, L. C. Xie, L. Jin
Exceptional point and spectral singularity are two types of singularity that are unique to non-Hermitian systems. Here, we report the high-order spectral singularity as a high-orde…
