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…

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…
