Abstract Topological pumps enable robust transports of topological states when the system parameters are varied in a cyclic process. The reported topological pumps are protected by the bulk topology. However, the exploration of topological pump prote

Abstract Exceptional points and skin effect, as the two distinct hallmark features unique to the non-Hermitian physics, have each attracted enormous interests. Recent theoretical works reveal that the topologically nontrivial exceptional points can g

Bulk and edge modes and their relation in topological materials is something researchers have been tried to harness for various applications. Here the authors provide a method to achieve chiral anomaly bulk states by applying boundary conditions to a

Flexible wave manipulations are crucial in the development of application for topological insulators. By stacking a 2D network of coupled acoustic resonators the authors demonstrate a 3D acoustic topological insulator with arbitrarily controllable di

Here, by constructing a heterostructure with sonic crystals, a topological waveguide is realized by the authors. The waveguide states feature gapless dispersion, momentum-valley locking, immunity against defects, and a high capacity for energy transp

Novel topological quasiparticles have attracted many interests recently. Here, He et al. observe quadratic Weyl points and identify double-helicoid surface arcs in sound waves traveling in a three-dimensional chiral metacrystal.

Underwater sound isolation has been a long-standing fundamental issue in industry and military fields. Starting from a simple theoretical model, here an air-sealed meta-screen is proposed to overcome this problem. Comparing with the sample without fi

Based on the Huygens-Fresnel principle, a metasurface structure is designed to generate a sound vortex beam in airborne environment. The metasurface is constructed by a thin planar plate perforated with a circular array of deep subwavelength resonato

In this work, we study the acoustically mediated interaction forces among multiple well-separated spherical particles trapped in the same node or antinode plane of a standing wave. An analytical expression of the acoustic interaction force is derived
