Breakdown effect of periodic perturbations to the robustness of topological phase in a gyromagnetic photonic crystal

Abstract In the known field of topological photonics, what remains less so is the breakdown effect of topological phases deteriorated by perturbation. In this study, the authors investigate the variance on topological invariants for a periodic Kekulé medium perturbed in unit cells, which was a gyrom...
