Twistsonics: engineering acoustic topological textures in moire sound lattices
Wen-Yu Wang, Shuai Liu, Xiang-Yuan Xu +4
Moire superlattices formed by twisting periodic systems provide a powerful platform for emergent topological phenomena, but their use for programming real-space topology in acousti…
