The research team led by Liu Zhengyou, Qiu Chunyin and Ke Manzhu, from the School of Physics and Technology of Wuhan University, has successively published two research achievements in the field of topological acoustics. One paper entitled "Observation of quadratic Weyl points and double-helicoid arcs" was published in Nature Communications. Another paper titled "Symmetry-enforced three-dimensi
