Two Classes of Singularities and Novel Topology in a Specially Designed Synthetic Photonic Crystals
Qiucui Li, Yu Zhang, Xunya Jiang
Zak phase and topological protected edge state are usually studied in one-dimensional(1D) photonic systems with spatial inversion symmetry(SIS). Interestingly in this work, we find…

The Connection of Topology between Systems with Different Dimensions: 1D Zak Phases to 2D Chern Number, Weyl Point as the Jumping Channel for One Singularity and Nodal Line to Merge All Singularities
Qiucui Li, Xunya Jiang
The topology in different dimensions has attracted enormous interests, e.g. the Zak phase in 1D systems, the Chern number in 2D systems and the Weyl points or nodal lines in the sy…
