Hybrid-order topological insulators in a phononic crystal
Yating Yang, Jiuyang Lu, Mou Yan +3
Topological phases, including the conventional first-order and higher-order topological insulators and semimetals, have emerged as a thriving topic in the fields of condensed-matte…
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…
Acoustic corner states in topological insulators with built-in Zeeman-like fields
Xueqin Huang, Jiuyang Lu, Zhongbo Yan +4
The higher-order topological insulators (HOTIs), with such as the topological corner states, emerge as a thriving topic in the field of topological physics. But few connections hav…
Acoustic square-root topological insulators
Mou Yan, Xueqin Huang, Li Luo +3
Square-root topological states are new topological phases, whose topological property is inherited from the square of the Hamiltonian. We realize the first-order and second-order s…
Higher-order topological semimetal in acoustic crystals
Qiang Wei, Xuewei Zhang, Weiyin Deng +6
The notion of higher-order topological insulators has endowed materials with topological states beyond the first order. Particularly, a three-dimensional (3D) higher-order topologi…
