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…

Acoustic helical dichroism enhanced by chiral quasi-bound states in the continuum
Qing Tong, Tong Fu, Yuqiong Cheng +1
Acoustic helical dichroism (HD) arises from the interaction between vortex beams carrying orbital angular momentum (OAM) and chiral media, yet such chiral sound-matter interactions…

Sculpturing sound fields with real-space topology
Qing Tong, Shubo Wang
Artificial structures have been widely used to manipulate sound fields. Most properties of these structures derive from the material and geometry. Few are explicitly related to the…
