Observation of non-Abelian nodal links in photonics
Erchan Yang, Biao Yang, Oubo You +8
In crystals, two bands may cross each other and form degeneracies along a closed loop in the three-dimensional momentum space, which is called nodal line. Nodal line degeneracy can…
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…
Large Chiroptical Effects in Planar Chiral Metamaterials
Weimin Ye, Xiaodong Yuan, Chucai Guo +3
Chiroptical effects, characterized by different optical responses for left- (LCP) and right- handed circularly polarized light (RCP), are powerful and valuable tools in optics with…
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…
