Relation between interface symmetry and propagation robustness along domain walls based on valley topological photonic crystals

Valley photonic crystals provide efficient designs for the routing of light through channels in extremely compact geometries. The topological origin of the robust transport and the specific geometries under which it can take place have been questioned in recent studies. In this article, we introduce...
