-Symmetric Topological Edge-Gain Effect
Alex Y. Song, Xiao-Qi Sun, Avik Dutt +6
We demonstrate a non-Hermitian topological effect that is characterized by having complex eigenvalues only in the edge states of a topological material, despite the fact that the m…

Constructing three-dimensional photonic topological insulator using two-dimensional ring resonator lattice with a synthetic frequency dimension
Qian Lin, Xiao-Qi Sun, Meng Xiao +2
In the development of topological photonics, achieving three dimensional topological insulators is of significant interest since it enables the exploration of new topological physi…
