Time reversal symmetric amorphous topological photonic crystal

摘要

The past decade has witnessed the prosperity of topological photonics.Starting from the proposal which realized the photonic quantum Hall effect in microwaves [1],there are subsequent analogs of almost all the nontrivial topological phases in photonics [2].Most of the photonic crystals(PCs)in these studies have specific lattices to exhibit nontrivial topology within a certain parameter range.
