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…
Control of Photon Dynamics in Non-Euclidean Polygonal Microcavities by Joint Geometric Curvatures
Yechun Ding, Yongsheng Wang, Peng Li +4
Non-Euclidean geometry has recently emerged as a powerful tool, offering new insights and applications in optical microcavities supporting Whispering Gallery Modes (WGMs). In this…
Vectorial Symmetry Decoding with Single-Particle Precision via Room-Temperature Lanthanide Luminescence Polarimetry
Peng Li, Yaxin Guo, Yaoxu Yan +10
Determining the local symmetry of luminescent centers in crystals is critical for understanding and controlling their optical transitions, yet current methods are limited by string…
Non-Gaussian Nature and Entanglement of Spontaneous Parametric Nondegenerate Triple-Photon Generation
D. Zhang, Y. Cai, Z. Zheng +4
How to prepare deterministically non-Gaussian entangled states is a fundamental question for continuous-variable quantum information technology. Here, we theoretically demonstrate…
Observation of Edge Solitons in Photonic Graphene
Zhaoyang Zhang, Rong Wang, Yiqi Zhang +8
Edge states emerge in diverse areas of science, offering new opportunities for the development of novel electronic or optoelectronic devices, sound and light propagation controls i…
Rabi-like oscillation of photonic topological valley Hall edge states
Hua Zhong, Yaroslav V. Kartashov, Yiqi Zhang +4
We investigate Rabi-like oscillations of topological valley Hall edge states by introducing two zigzag domain walls in an inversion-symmetry-breaking honeycomb photonic lattice. Su…
