Observation of a phononic higher-order Weyl semimetal
Li Luo, Hai-Xiao Wang, Bin Jiang +4
Weyl semimetals are extraordinary systems where exotic phenomena such as Fermi arcs, pseudo-gauge fields and quantum anomalies arise from topological band degeneracy in crystalline…
On-chip higher-order topological micromechanical metamaterials
Ying Wu, Mou Yan, Hai-Xiao Wang +2
Higher-order topological insulators exhibit multidimensional topological physics and unique application values due to their ability of integrating stable boundary states at multipl…
Higher-Order Weyl Semimetals
Hai-Xiao Wang, Zhi-Kang Lin, Bin Jiang +2
Higher-order topology yields intriguing multidimensional topological phenomena, while Weyl semimetals have unconventional properties such as chiral anomaly. However, so far, Weyl p…
Higher-order topological spin Hall effect of sound
Zhi-Kang Lin, Shi-Qiao Wu, Hai-Xiao Wang +1
We propose theoretically a reconfigurable two-dimensional (2D) hexagonal sonic crystal with higher-order topology protected by the six-fold, , rotation symmetry. The acoustic…
Corner states and topological transitions in two-dimensional higher-order topological sonic crystals with inversion symmetry
Zhan Xiong, Zhi-Kang Lin, Hai-Xiao Wang +4
Macroscopic two-dimensional sonic crystals with inversion symmetry are studied to reveal higher-order topological physics in classical wave systems. By tuning a single geometry par…
Experimental discovery of bulk-disclination correspondence
Yang Liu, Shuwai Leung, Fei-Fei Li +4
Most natural and artificial materials have crystalline structures from which abundant topological phases emerge [1-6]. The bulk-edge correspondence, widely-adopted in experiments t…
