Possible Realization of Optical Quadratic and Dirac Points in Woodpile Photonic Crystals
Hai-Xiao Wang, Yige Chen, Guang-Yu Guo +2
The simulation of fermionic relativistic physics, e.g., Dirac and Weyl physics, has led to the discovery of many unprecedented phenomena in photonics, of which the optical-frequenc…
Type-II Dirac Photons
Hai-Xiao Wang, Yige Chen, Zhi Hong Hang +2
The Dirac equation for relativistic electron waves is the parent model for Weyl and Majorana fermions as well as topological insulators. Simulation of Dirac physics in three-dimens…
3D Topological Nodes in Nonsymmorphic Photonic Crystals: Ultrastrong Coupling and Anomalous Refraction
Hai-Xiao Wang, Yige Chen, Zhi Hong Hang +2
We propose to simulate 3D Dirac points and line-nodes with nontrivial topology in nonsymmorphic all-dielectric photonic-crystals with space-time reversal symmetry, which can…
