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…
Acoustic spin-1 Weyl semimetal
Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topological semimetal, hosting spin-1 Weyl point beyond Dirac and Weyl points, has attracted a great deal of attention. However, the spin-1 Weyl semimetal, which possesses exclusiv…
Acoustic spin-Chern insulator induced by synthetic spin-orbit coupling with spin conservation breaking
Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topologically protected surface modes of classical waves hold the promise to enable a variety of applications ranging from robust transport of energy to reliable information proces…
Ideal type-II Weyl phase and topological transition in phononic crystals
Xueqin Huang, Jiuyang Lu, Feng Li +2
Ideal Weyl points, which are related by symmetry and thus reside at the same frequency, could promote the deep development and utilization of the Weyl physics. Although the ideal t…
