Observation of Square-Root Higher-Order Topological States in Photonic Waveguide Arrays
Juan Kang, Tao Liu, Mou Yan +7
Recently, high-order topological insulators (HOTIs), accompanied by topologically nontrivial boundary states with codimension larger than one, have been extensively explored becaus…
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…
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…
