Localization of chiral edge states by the non-Hermitian skin effect
Gui-Geng Liu, Subhaskar Mandal, Peiheng Zhou +11
Quantum Hall systems host chiral edge states extending along the one-dimensional boundary of any two-dimensional sample. In solid state materials, the edge states serve as perfectl…
Observation of Weyl point pair annihilation in a gyromagnetic photonic crystal
Gui-Geng Liu, Zhen Gao, Peiheng Zhou +9
Weyl semimetals are gapless three-dimensional (3D) phases whose bandstructures contain Weyl point (WP) degeneracies. WPs carry topological charge and can only be eliminated by mutu…
Observation of photonic antichiral edge states
Peiheng Zhou, Gui-Geng Liu, Yihao Yang +6
Chiral edge states are a hallmark feature of two-dimensional topological materials. Such states must propagate along the edges of the bulk either clockwise or counterclockwise, and…
Ideal Unconventional Weyl Point in a Chiral Photonic Metamaterial
Yihao Yang, Zhen Gao, Xiaolong Feng +5
Unconventional Weyl points (WPs), carrying topological charge 2 or higher, possess interesting properties different from ordinary charge-1 WPs, including multiple Fermi arcs that s…
