Topological materials or structures: Origin of higher-order topological states
Shengjie Zheng, Guiju Duan, Jianting Liu +1
Higher-order topological states (HOTS) have been extensively investigated in classical wave systems. They do not exist in the band gaps of infinite materials, while exhibit as the…
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.…
