Visualized Geometric Phase of Caustic Geometric Beams
Haiyang Li, Yijie Shen
Detecting Pancharatnam-Berry geometric phases of light typically requires interferometry or diffraction through a specially truncated aperture. Here, we introduce a simpler method…
Freespace twistronics for optical supertopologies
Vasu Dev, Yijie Shen
Twistronics, the study of moiré superlattices of twisted bilayer 2D materials creating nontrivial physical effects, has recently revolutionized diverse subjects from materials to o…
Tailoring ultra-high-order optical skyrmions
Xinji Zeng, Jing Fang, Haijun Wu +9
Skyrmions, as quasiparticles with topological spin textures, has recently garnered great attention for both condensed matter and structured wave communities, promising next-generat…
Photonic torons, topological phase transition and tunable spin monopoles
Haijun Wu, Nilo Mata-Cervera, Haiwen Wang +3
Creation and control of topological complex excitations play crucial roles in both fundamental physics and modern information science. Torons are a sophisticated class of 3D chiral…
Spintwistronics: Photonic bilayer topological lattices tuning extreme spin-orbit interactions
Peng Shi, Xinxin Gou, Qiang Zhang +6
Twistronics, the manipulation of Moiré superlattices via the twisting of two layers of two-dimensional (2D) materials to control diverse and nontrivial properties, has recently rev…
Generalized Skyrmions
An Aloysius Wang, Zimo Zhao, Yifei Ma +10
Skyrmions are important topologically non-trivial fields characteristic of models spanning scales from the microscopic to the cosmological. However, the Skyrmion number can only be…
Fully Tunable On-Chip Meta-Generator for Multidimensional Poincaré Sphere mapping
Jing Luan, Tiange Wu, Shuang Zheng +7
The angular momentum of light can be elegantly mapped onto high-order Poincare spheres, providing a powerful framework for describing structured light beams. Such beams have shown…
