HIGHLIGHTS
- who: Yijie Shen and colleagues from the University of Southampton, Optoelectronics Research Centre and Centre for Photonic Metamaterials, Southampton, United Kingdom have published the research: Topological transformation and free-space transport of photonic hopfions, in the Journal: (JOURNAL) of 06/02/2023
- what: The authors propose and demonstrate photonic counterparts of hopfions with exact characteristics of Hopf fibration Hopf index and Hopf mapping from real-space vector beams to homotopic hyperspheres representing polarization states.
- how: The authors presented both theoretical and experimental demonstrations of reconfigurable higher-order hopfionic textures and their free-space . . .
