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…
