摘要

With the support by the National Natural Science Foundation of China,the research team led by Prof.Lu MingHui (卢明辉) and Prof.Chen YanFeng (陈延峰) at the National Laboratory of Solid State Microstructures,Department of Materials Science and Engineering,Nanjing University,has realized the higher-order topological insulators (HOTIs) in two-dimensional (2D) sonic crystals (SCs).This work was conducted in collaboration with the group led by Prof.Jiang JianHua (蒋建华) from Soochow University,and published in Nature Physics (doi:10.1038/s41567-019-0472-1).
