Optical hopfions with arbitrary two winding numbers
Xinji Zeng, Jinwen Wang, Yun Chen +10
Hopfions, as three-dimensional topologically nontrivial structures described by poloidal and toroidal winding numbers, hold promise as robust information carriers in spintronics, f…
Storage and retrieval of optical skyrmions with topological characteristics
Jinwen Wang, Xin Yang, Yun Chen +10
Optical skyrmions are topological structures of light whose defining property, the skyrmion number, is robust against perturbations. This makes them attractive for applications in…
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…
Quantum delayed "choice" based on vectorially structured photon
Ye Yang, Shuya Zhang, Yongkun Zhou +7
Whether a photon exhibits wavelike or particlelike behaviour depends on the observation method, as clearly demonstrated by Wheeler's delayed choice (DC) experiments. A key aspect o…
