Pseudospin-dependent Acoustic Topological Insulator by Sonic Crystals With Same Hexagonal Rods
We report the experimental and numerical realization of a pseudospin-dependent acoustic topological insulator based on two sonic crystals constructed by the same regular hexagonal rods. Based on the zone folding mechanism, we obtain double Dirac cones with a four-fold deterministic degeneracy in the...
