Acoustic realization of quadrupole topological insulators
Yajuan Qi, Chunyin Qiu, Meng Xiao +3
A quadrupole topological insulator, being one higher-order topological insulator with nontrivial quadrupole quantization, has been intensely investigated very recently. However, th…

Symmetry-enforced three-dimensional Dirac phononic crystals
Xiangxi Cai, Liping Ye, Chunyin Qiu +4
Dirac semimetals, the materials featured with discrete linearly crossing points (called Dirac points) between four bands, are critical states of topologically distinct phases. Such…
