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…
Observation of photonic Fermi arcs in topological metamaterials
Biao Yang, Qinghua Guo, Ben Tremain +8
The discovery of topological phases introduces new perspectives and platforms for various interesting physics originally investigated in quantum context and then, on an equal footi…
Three dimensional photonic Dirac points in metamaterials
Qinghua Guo, Biao Yang, Lingbo Xia +5
Topological semimetals, representing a new topological phase that lacks a full bandgap in bulk states and exhibiting nontrivial topological orders, recently have been extended to p…
Controlling plasmonic orbital angular momentum by combining geometric and dynamic phases
Qilong Tan, Qinghua Guo, Hongchao Liu +2
Tunable orbit angular momentum (OAM) of surface plasmon polaritons (SPPs) is theoretically studied with appropriately designed metasurfaces. By controlling both the orientation ang…
