Topological phenomena demonstrated in photorefractive photonic lattices
Shiqi Xia, Daohong Song, Nan Wang +5
Topological photonics has attracted widespread research attention in the past decade due to its fundamental interest and unique manner in controlling light propagation for advanced…
Valley-dependent wavepacket self-rotation and Zitterbewegung in symmetry-broken honeycomb lattices
Xiuying Liu, Frane Lunić, Daohong Song +6
The toolbox quantities used for manipulating the flow of light include typically amplitude, phase, and polarization. Pseudospins, such as those arising from valley degrees of freed…
Universal momentum-to-real-space mapping of topological singularities
Xiuying Liu, Shiqi Xia, Ema Jajtić +7
Topological properties of materials, as manifested in the intriguing phenomena of quantum Hall effect and topological insulators, have attracted overwhelming transdisciplinary inte…
Valley vortex states and degeneracy lifting via photonic higher-band excitation
Daohong Song, Daniel Leykam, Jing Su +7
We demonstrate valley-dependent vortex generation in a photonic graphene. Without breaking the inversion symmetry, excitation of two equivalent valleys leads to formation of an opt…
Unconventional Flatband Line States in Photonic Lieb Lattices
Shiqi Xia, Ajith Ramachandran, Shiqiang Xia +9
Flatband systems typically host "compact localized states"(CLS) due to destructive interference and macroscopic degeneracy of Bloch wave functions associated with a dispersionless…
