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…
