Understanding the connections between skyrmions and other topological solitons in magnets is crucial. I will provide an alternative perspective on this topic in the following video.
Like skyrmions -- vortices localized in a 2D magnet, hopfions are 3D localized knots constructed from magnetic spins. The torus, you see here, is the simplest example of hopfions.
Very nice visualizations! What software have you carried out these simulations with?
I use this software: github.com/n-s-kiselev/magnoom
with some slight modifications.
Why in the Skyrmion am I watching this?

Please tell me what this is
Magnets!
