Observation of Emergent Dirac Physics at the Surfaces of Acoustic Higher‐Order Topological Insulators
Using 3D sonic crystals as acoustic higher‐order topological insulators (HOTIs), 2D surface states described by spin‐1 Dirac equations at the interfaces between the two sonic crystals with distinct topology but the same crystalline symmetry are discovered. It is found that the Dirac mass can be tune...
