Spin-to-orbital angular momentum conversion in non-Hermitian photonic graphene
Zhaoyang Zhang, Pavel Kokhanchik, Zhenzhi Liu +7
Optical beams with orbital angular momentum (OAM) have numerous potential applications, but the means used for their generation often lack crucial on-demand control. In this work,…
Observation of nonreciprocal transverse localization of light
Shun Liang, Changchang Li, Wenqing Yu +7
Magnetic-free nonreciprocal optical devices that can prevent backscattering of signals are essential for integrated optical information processing. The achieved nonreciprocal behav…
Beam dynamics induced by the quantum metric of exceptional rings
Zhaoyang Zhang, Ismaël Septembre, Zhenzhi Liu +10
Topological physics has broadened its scope from the study of topological insulating phases to include nodal phases containing band structure singularities. The geometry of the cor…
Non-Hermitian delocalization in a 2D photonic quasicrystal
Zhaoyang Zhang, Shun Liang, Ismael Septembre +7
Quasicrystals show long-range order, but lack translational symmetry. So far, theoretical and experimental studies suggest that both Hermitian and non-Hermitian quasicrystals show…
