Hybrid skin-topological effect induced by eight-site cells and arbitrary adjustment of the localization of topological edge states
Jianzhi Chen, Aoqian Shi, Yuchen Peng +2
The hybrid skin-topological effect (HSTE) in non-Hermitian systems exhibits both the skin effect and topological protection, offering a novel mechanism for the localization of topo…
Aperiodic-quasiperiodic-periodic properties and topological transitions in twisted nested Moiré patterns
Peng Peng, Yuchen Peng, Aoqian Shi +3
The Moiré patterns generated by altering the structural parameters in a two or more layers of periodic materials, including single-layer structure, interlayer stacking, and twistin…
Pseudospin-Induced Asymmetric Field in Non-Hermitian Photonic Crystals with Multiple Topological Transitions
Yuchen Peng, Aoqian Shi, Peng Peng +1
We report the discovery of multiple topological phase transitions induced by the photonic quantum spin Hall effect (PQSHE) in a non-Hermitian photonic crystal (PhC). When increasin…
Observation of Topological Corner State Arrays in Photonic Quasicrystals
Aoqian Shi, Yiwei Peng, Jiapei Jiang +8
Recently, the studies of topological corner states (TCSs) are extended from crystals to quasicrystals, which are referred to as higher-order topological quasicrystalline insulators…
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…
