Symmetry-enforced three-dimensional Dirac phononic crystals
Xiangxi Cai, Liping Ye, Chunyin Qiu +4
Dirac semimetals, the materials featured with discrete linearly crossing points (called Dirac points) between four bands, are critical states of topologically distinct phases. Such…
Topological negative refraction of surface acoustic waves in a Weyl phononic crystal
Hailong He, Chunyin Qiu, Liping Ye +5
Reflection and refraction occur at interface between two different media. These two fundamental phenomena form the basis of fabricating various wave components. Specifically, refra…
Valley-projected edge modes observed in underwater sonic crystals
Yuanyuan Shen, Chunyin Qiu, Xiangxi Cai +4
Recently, the topological physics in acoustics has been attracting much attention. However, all the studies are aimed to elastic or airborne sound systems. Realizing topological in…
Observation of acoustic Landau quantization and quantum-Hall-like edge states
Xinhua Wen, Chunyin Qiu, Yajuan Qi +4
Many intriguing phenomena occur for electrons under strong magnetic fields. Recently, it was proposed that an appropriate strain texture in graphene can induce a synthetic gauge fi…
Observation of topological valley transport of sound in sonic crystals
Jiuyang Lu, Chunyin Qiu, Liping Ye +4
Valley pseudospin, labeling quantum states of energy extrema in momentum space, is attracting tremendous attention1-13 because of its potential in constructing new carrier of infor…
Making sound vortices by metasurfaces
Liping Ye, Chunyin Qiu, Jiuyang Lu +5
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…
