Three-dimensional topological acoustic crystals with pseudospin-valley coupled saddle surface states
Topological valley states at the domain wall between two artificial crystals with opposite valley Chern numbers offer a feasible way to realize robust wave transport since only broken spatial symmetry is required. In addition to the valley, spin and crystal dimension are two other important degrees...
