Topological property of graphene with triangular array of nanoholes
Yong-Cheng Jiang, Xing-Xiang Wang, Xiao Hu
The nontrivial band topology for graphene with regular arrays of nanoholes with symmetry is investigated theoretically. For the case of triang…
Periodic Behavior of Topology in Graphene with Nanohole Array
Yong-Cheng Jiang, Xing-Xiang Wang, Xiao Hu
We derive a way to diagnose band topology for graphene with triangular and/or honeycomb array of nanoholes directly from the lattice constant of superstructure $m\sqrt{3}\times m\s…
Magneto-optical Skyrmion for manipulation of arbitrary light polarization
Xinghong Chen, Xingxiang Wang, Guanjie Zhang +4
Dynamic manipulation of arbitrary light polarization is of fundamental importance for versatile optical functionalities, yet realizing such full-Poincaré-sphere control within comp…
Comment on "Absence of Topological Protection of the Interface States in Photonic Crystals"
Xing-Xiang Wang, Toshikaze Kariyado, Xiao Hu
In the Letter, Xu et al. reported that edge modes disappear in the expanded structure of Wu-Hu model characterized by topological index, while appear in the trivial…
Interference and switching effect of topological interfacial modes with geometric phase
Xing-Xiang Wang, Tomohiro Amemiya, Xiao Hu
We investigate interference between topological interfacial modes in a semiconductor photonic crystal platform with Dirac frequency dispersions, which can be exploited for interfer…
