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…
Floquet Chern Vector Topological Insulators in Three Dimensions
Fangyuan Ma, Junrong Feng, Feng Li +2
We theoretically and numerically investigate Chern vector insulators and topological surface states in a three-dimensional lattice, based on phase-delayed temporal-periodic interac…
Fully-Polarized Topological Isostatic Metamaterials in Three Dimensions
Zheng Tang, Fangyuan Ma, Feng Li +2
Topological surface states are unique to topological materials and are immune to disturbances. In isostatic lattices, mechanical topological floppy modes exhibit softness depending…
Probing fragile topology with a screw dislocation
Ying Wu, Zhi-Kang Lin, Yating Yang +3
Fragile topology, akin to twisted bilayer graphene and the exotic phases therein, is a notable topological class with intriguing properties. However, due to its unique nature and t…
