Skyrmions are topologically stable quasiparticles that have been predicted and
demonstrated in quantum fields, solid-state physics and magnetic materials, but only …

The field of magnetic skyrmions has been actively investigated across a wide range of topics
during the last decades. In this topical review, we mainly review and discuss key results and …

Orbital angular momentum (OAM) of light is an important feature of structured
electromagnetic fields exhibiting non-uniform spatial distribution. In contrast to a spin …

Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

We construct optical beams in free space with robust skyrmionic structures in their
polarization fields, both in the electric spin vector for near-circular fields and in the …

Quantization effects of the nonlinear magnon-vortex interaction in ferromagnetic nanodisks
are studied. We show that the circular geometry twists the spin-wave fields with spiral phase …

We report on the experimental evidence of magnetic helicoidal dichroism, observed in the
interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a …

Skyrmions are topologically stable quasiparticles that have been predicted and
demonstrated in quantum fields, solid-state physics, and magnetic materials, but only …

Wave fields with spiral phase dislocations carrying orbital angular momentum (OAM) have
been realized in many branches of physics, such as for photons, sound waves, electron …

In condensed matter systems it is necessary to distinguish between the momentum of the
constituents of the system and the pseudomomentum of quasiparticles. The same distinction …
