Quadrupole topological behavior of elastic waves in two-dimensional square lattices with nonsymmorphic symmetries
Yijie Liu, Yuyang Chen, Zhaoyang Guo +4
We investigate a novel higher-order topological behavior in elastic lattices characterized by nonsymmorphic symmetries. In the theoretical spring-mass lattice, altering the vertex…

Acoustic Three-dimensional Chern Insulators with Arbitrary Chern Vectors
Yang Linyun, Xi Xiang, Meng Yan +13
The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phase of three-dimensional (3D) Chern insulators. Such a vecto…
