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…
Observation of quadratic Weyl points and double-helicoid arcs
Hailong He, Chunyin Qiu, Xiangxi Cai +4
Very recently, novel quasiparticles beyond those mimicking the elementary high-energy particles such as Dirac and Weyl fermions have attracted great interest in condensed matter ph…
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…
