Abstract

Author(s): Ting-Gui Chen, Jun-Rui Jiao, Hong-Qing Dai, and De-Jie Yu We show that acoustic double Weyl points are observed in a square lattice by breaking inversion symmetry. We also show that the double Weyl points are protected by the ${C}_{4}$ rotation symmetry but are unaffected by translation symmetry along the $z$ direction. When ${C}_{4}$ rotation symmetry is ...
