Topological phononics
Zeguo Chen, Tiantian Zhang, Xulong Wang +12
Topological phononics extends the foundational concepts of topological condensed matter physics to the realm of lattice vibrations and classical mechanical waves, unlocking robust,…
Demonstration of acoustic high-order Stiefel-Whitney semimetal in bilayer graphene sonic crystals
Xiao Xiang, Xiang Ni, Feng Gao +4
Recently, higher-order topological phases have endowed materials many exotic topological phases. For three-dimensional (3D) higher-order topologies, it hosts topologically protecte…
Multifrequency and multimode topological waveguides in a Stampfli-triangle photonic crystal with large valley Chern numbers
Bei Yan, Yiwei Peng, Jianlan Xie +9
The multifrequency quantum valley Hall effect (QVHE) with a large valley Chern number has been realized to significantly improve the transmission capacity of topological waveguides…
Frequency tunable topological edge states of two-dimensional honeycomb lattice photonic crystals
Yuchen Peng, Bei Yan, Jianlan Xie +5
In this paper, the photonic quantum spin Hall effect (PQSHE) is realized in dielectric two-dimensional (2D) honeycomb lattice photonic crystal (PC) by stretching and shrinking the…
