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…
Nonreciprocal spontaneous parametric process
Changbiao Li, Jiaqi Yuan, Ruidong He +5
Mediated by the interaction with quantum vacuum fields, a laser field propagating in a nonlinear optical medium can generate new light fields via spontaneous parametric process. Su…
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…
Simultaneous creation of multiple vortex-antivortex pairs in momentum space in photonic lattices
Feng Li, S. V. Koniakhin, A. V. Nalitov +6
Engineering of the orbital angular momentum (OAM) of light due to interaction with photonic lattices reveals rich physics and motivates potential applications. We report the experi…
Angular-dependent Klein tunneling in photonic graphene
Zhaoyang Zhang, Yuan Feng, Feng Li +7
The Klein paradox consists in the perfect tunneling of relativistic particles through high potential barriers. As a curious feature of particle physics, it is responsible for the e…
