Analogies between non-trivial topologies of matter and light have inspired numerous studies, including defect formation in structured light and topological photonic band structures. Three-dimensional topological objects of localised particle-like nature attract broad interest across discipline boundaries from elementary particle physics and cosmology to condensed matter physics. Here we propose how simple structured light beams can be transformed into optical excitations of atoms with… 
Optical magnetism and wavefront control by arrays of strontium atoms
(Dated: By analyzing the parameters of electronic transitions, we show how bosonic Sr atoms in planar optical lattices can be engineered to exhibit optical magnetism and other higher-order
Topologically driven Rabi-oscillating interference dislocation
Abstract Quantum vortices are the quantized version of classical vortices. Their center is a phase singularity or vortex core around which the flow of particles as a whole circulates and is typical
Topological quasiparticles of light: Optical skyrmions and beyond
Skyrmions are topologically stable quasiparticles that have been predicted and demonstrated in quantum fields, solid-state physics, and magnetic materials, but only recently observed in


Optical skyrmion lattice in evanescent electromagnetic fields
It is shown that optical skyrmion lattices can be generated using evanescent electromagnetic fields and demonstrated using surface plasmon polaritons, imaged by phase-resolved near-field optical microscopy and shown how the optical sk Kyrmions lattice exhibits robustness to imperfections while the topological domain walls in the lattice can be continuously tuned.
Diversity of knot solitons in liquid crystals manifested by linking of preimages in torons and hopfions
Topological solitons are knots in continuous physical fields classified by non-zero Hopf index values. Despite arising in theories that span many branches of physics, from elementary particles to
Twist of generalized skyrmions and spin vortices in a polariton superfluid
It is demonstrated that the presence of a polarization anisotropy can induce a complex dynamics of these structured topologies, leading to the twist of their circuitation on the Poincaré sphere of polarizations.
Synthetic electromagnetic knot in a three-dimensional skyrmion
The results reveal the versatile capabilities of synthetic electromagnetism and provide the first experimental images of topological three-dimensional skyrmions in a quantum system.
Skyrmions in a ferromagnetic Bose–Einstein condensate
It is found that skyrmions can exist in such a gas only as a metastable state, but with a lifetime comparable to (or even longer than) the typical lifetime of the condensate itself.
Observation of second-order meron polarization textures in optical microcavities
Multicomponent Bose-Einstein condensates, quantum Hall systems, and chiral magnetic materials display twists and knots in the continuous symmetries of their order parameter, known as Skyrmions.
Stationary ring solitons in field theory - knots and vortons
Isolated optical vortex knots
Guided by a general framework for wavefront engineering, experiments demonstrate that in a light field, lines of zero intensity can be shaped into knotted and linked loops of arbitrary topology.
Ultrafast vector imaging of plasmonic skyrmion dynamics with deep subwavelength resolution
A new technique, time-resolved vector microscopy, is introduced that enables us to compose entire movies on a subfemtosecond time scale and a 10-nm spatial scale of the electric field vectors of surface plasmon polaritons (SPPs).
Deep-subwavelength features of photonic skyrmions in a confined electromagnetic field with orbital angular momentum
In magnetic materials, skyrmions are nanoscale regions where the orientation of the electron spin changes in a vortex-type manner1–4. Electromagnetic waves carry both spin and orbital angular
