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…

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…
