Robustness of topological corner modes in photonic crystals
We analyze the robustness of corner modes in topological photonic crystals, taking a C_{6}-symmetric breathing honeycomb photonic crystal as an example. First, we employ topological quantum chemistry and Wilson loop calculations to demonstrate that the topological properties of the bulk crystal stem...
