Photonic topological Anderson insulators
Xiaohan Cui, Ruo-Yang Zhang, Zhao-Qing Zhang +1
That disorder can induce nontrivial topology is a surprising discovery in topological physics. As a typical example, Chern topological Anderson insulators (TAIs) have been realized…
Topological one-way large-area waveguide states in magnetic photonic crystals
Mudi Wang, Ruo-Yang Zhang, Lei Zhang +4
We have theoretically and experimentally achieved large-area one-way transport by using heterostructures consisting of a domain of an ordinary photonic crystal (PC) sandwiched betw…
Optical pulling using topologically protected one-way-transport surface-arc waves
Neng Wang, Ruo-Yang Zhang, Qinghua Guo +2
This paper proposes a new method to achieve robust optical pulling of particles by using an air waveguide sandwiched between two chiral hyperbolic metamaterials. The pulling force…
Hidden-symmetry-enforced nexus points of nodal lines in layer-stacked dielectric photonic crystals
Zhongfei Xiong, Ruo-Yang Zhang, Rui Yu +2
It was recently demonstrated that the connectivities of bands emerging from zero frequency in dielectric photonic crystals are distinct from their electronic counterparts with the…
Interlayer Topological Transport and Devices based on Layer Pseudospins in Photonic Valley-Hall Phases
Xiaoxiao Wu, Zhenyu Li, Jian Chen +8
Valley-Hall phases, first proposed in two-dimensional (2D) materials, originate from nontrivial topologies around valleys which denote local extrema in momentum space. Since they a…
Observation of Three-dimensional Photonic Dirac points and Spin-polarized Surface Arcs
Qinghua Guo, Oubo You, Biao Yang +9
Topological phases arise from the elegant mathematical structures imposed by the interplay between symmetry and topology1-5. From gapped topological insulators to gapless semimetal…
