Annihilation of Dirac points and its topological obstruction in a photonic Kagome lattice
Zhaoyang Zhang, Matthieu Finck, Changchang Li +7
Dirac points (DPs) are topological singularities that determine the extraordinary properties of two-dimensional materials. They are generally classified by discrete topological inv…
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…
Loss-difference-induced localization in a non-Hermitian honeycomb photonic lattice
Yuan Feng, Zhenzhi Liu, Fu Liu +6
Non-Hermitian systems with complex-valued energy spectra provide an extraordinary platform for manipulating unconventional dynamics of light. Here, we demonstrate the localization…
Spin-orbit coupling in photonic graphene
Zhaoyang Zhang, Shun Liang, Feng Li +6
We generate experimentally a honeycomb refractive index pattern in an atomic vapor cell using electromagnetically-induced transparency. We study experimentally and theoretically th…
