Journal ArticleDOI
Acoustic topological insulator and robust one-way sound transport
TL;DR: In this article, the acoustic analogue of a topological insulator is shown: a metamaterial exhibiting one-way sound transport along its edge, a graphene-like array of stainless-steel rods.
Journal ArticleDOI
Breaking the barriers: advances in acoustic functional materials
TL;DR: In this article, the authors present a review of recent developments in the field of acoustic metamaterials, including zero/negative refraction, subwavelength imaging, sound cloaking, total sound absorption, metasurface and phase engineering, Dirac physics and topology-inspired acoustic engineering, non-Hermitian parity-time synthetic active active metammaterials, and one-way propagation of sound waves.
Journal ArticleDOI
Observation of zone folding induced acoustic topological insulators and the role of spin-mixing defects
TL;DR: In this paper, a flow-free, pseudospin-based acoustic topological insulator designed using the strategy of zone folding is demonstrated with the presence of non-spin-mixing defects.

TL;DR: In this article, the acoustic Weyl points and surface Fermi arcs in a phononic crystal were shown to be robust to backscattering in 3D topologically nontrivial states in acoustic systems.
Journal ArticleDOI
Three-dimensional topological acoustic crystals with pseudospin-valley coupled saddle surface states.

TL;DR: It is experimentally demonstrated that it is possible to construct two-dimensional acoustic topological pseudospin-valley coupled saddle surface states, designed from glide symmetry in a three-dimensional system, and multi-directional anisotropic controllable robust sound transport with little backscattering is observed.
