Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices
Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Field-tuned spin excitation spectrum of kπ skyrmion
New Journal of Physics, 2019 We study spin wave excitation modes of kπ skyrmion ( k = 1, 2, 3) in a magnetic nanodot under an external magnetic field along the z direction using micromagnetic simulations based on the Landau–Lifshitz–Gilbert equation. We find that a transition of kπ

Motion of skyrmions in nanowires driven by magnonic momentum-transfer forces
New Journal of Physics, 2017 We study the motion of magnetic skyrmions in a nanowire induced by a spin-wave current J flowing out of a driving layer close to the edge of the wire. By applying micromagnetic simulation and an analysis of the effective Thiele equation, we find that the

Communications in Mathematical Physics, 1987 A Skyrmion is a classical static field configuration of minimal energy in a nonlinear scalar field theory, where the Skyrmion represents a baryon and the scalar field is given by the pion. Mathematically a Skyrmion can be regarded as a topological non-trivial map from one Riemannian manifold to another (3-dimensional, orientable, connected), and the ...
