Observation of fractal topological states in acoustic metamaterials
Shengjie Zheng, Xianfeng Man, Ze-Lin Kong +6
Topological phases of matter have been extensively investigated in solid state materials and classical wave systems with integer dimensions. However, topological states in non-inte…
Three-dimensional higher-order topological acoustic system with multidimensional topological states
Baizhan Xia, Shengjie Zheng, Liang Tong +3
Topologically protected gapless edge/surface states are phases of quantum matter which behave as massless Dirac fermions, immunizing against disorders and continuous perturbations.…
Acoustic semimetal with Weyl points and surface states
Tingting Liu, Shengjie Zheng, Hongqing Dai +2
Two-dimensional topological edge states, immunizing against defects and disorders, have greatly revolutionized our scientific cognition on propagation and scattering of acoustic wa…
