Acoustic toroidal vortices with programmable links and knots
Shuai Liu, Xiang-Yuan Xu, Hao Ge +3
Toroidal vortices are three-dimensional torus-shaped wave structures characterized by phase circulation around a closed vortex line. Their toroidal geometry provides a natural foun…
Non-diffracting meronic spin defects of light
Nilo Mata-Cervera, Miguel A. Porras, Yijie Shen
Optical vortices are singularity lines where the light field intensity vanishes and its phase is undefined. These threads of darkness are adorned by Gauss's law as lines of pure lo…
Simultaneous Superoscillations in Space and Time in Nonseparable Light Pulses
Yijie Shen, Nikitas Papasimakis, Nikolay I. Zheludev
A remarkable phenomenon of superoscillations implies that electromagnetic waves can locally oscillate in space or time faster than the fastest spatial and temporal Fourier componen…
Topological optical skyrmion transfer to matter
Chirantan Mitra, Chetan Sriram Madasu, Lucas Gabardos +4
The ability of structured light to mimic exotic topological skyrmion textures, encountered in high-energy physics, cosmology, magnetic materials, and superfluids has recently recei…
Optical skyrmion lattices accelerating in free space
Haijun Wu, Weijie Zhou, Zhihan Zhu +1
Generation and propagation of optical skyrmions provide a versatile plalform for topologically nontrivial optical informatics and light-matter interactions, but their acceleration…
Observation of helical pulses
Ren Wang, Shuai Shi, Zeyi Zhang +4
Ultrafast spatiotemporal vortex pulses constitute a category within spatiotemporal topological waves. Nevertheless, the experimental realization of helical pulses single or few cyc…
Double-Helix Singularity and Vortex-Antivortex Annihilation in Space-Time Helical Pulses
Shuai Shi, Ren Wang, Minhui Xiong +3
Topological structures reveal the hidden secrets and beauty in nature, such as the double helix in DNA, whilst, the manipula-tion of which in physical fields, especially in ultrafa…
Hybrid electromagnetic toroidal vortices

Hopfions, higher-dimensional topological quasiparticles with sophisticated 3D knotted spin textures discovered in condensed matter and photonic systems, show promise in high-densit…
Propagation-invariant strongly longitudinally polarized toroidal pulses
Ren Wang, Ding-Tao Yang, Tao Xin +3
Recent advancements in optical, terahertz, and microwave systems have unveiled non-transverse optical toroidal pulses characterized by skyrmionic topologies, fractal-like singulari…
Generation of tunable optical skyrmions on Skyrme-Poincaré sphere
Yijie Shen, Eduardo Casas Martínez, Carmelo Rosales-Guzmán
In recent time, the optical-analogous skyrmions, topological quasiparticles with sophisticated vectorial structures, have received an increasing amount of interest. Here we propose…
