There are ghostly shapes hidden in magnetic fields.
They're not made of stuff in the way a lightning bolt or a beam of light is. A lighting bolt carries a fairly defined group of electrons from the sky all the way to the ground....
But magnetic fields contain things called skyrmions that are different from electrons and photons; a skyrmion is a knot of magnetic field lines looping around each other. As it drifts from one spot to the next, a skyrmion makes itself anew out of the magnetic field lines that are already there. The knot holds together because magnetic field lines resist passing through one another. So, while skyrmions are insubstantial and different from objects we're used to thinking about, they act like more tangible things.
Physicists call these skyrmions "quasiparticles," and suspect they could explain phenomena as disparate as ball lightning and the nuclear structure of an atom. Now, in a new paper, researchers showed that skyrmions can be stuffed inside one another, taking on a completely new shape. These puffed-up "skyrmion bags" are fascinating objects in their own right, but the bizarre things might also be useful for futuristic computing, the researchers said.
The team revealed the skyrmion bags in a paper published April 1 in the journal Nature Physics. The result relies on a key similarity between the ghostly quasiparticles and solid matter: the existence of antiparticles.
Just like protons have counterpart antiprotons that annihilate each other on contact with each other, skyrmions have antiskyrmions.
So, if a magnetic field line points north in a skyrmion, it would point south in an antiskyrmion. But antiskyrmions and skyrmions powerfully repel one another...
What's more, the researchers realized, once a skyrmion has been stretched, you can stuff even more antiskyrmions inside it.

Sounds like a description of Hillary Clinton. Although she's anything but magnetic.

Sadly, William F. Buckley did not live to see the antiskyrmionism he went off in search of ...
“One particular form of skyrmions is magnetic skyrmions, found in magnetic materials that exhibit spiral magnetism due to the Dzyaloshinskii-Moriya interaction, double-exchange mechanism or competing Heisenberg exchange interactions.”
This is an episode of Big Bang Theory, right?

Great gif!
“Skyrmion Bags”
I think I have to re-register on FR with a new screen name.
Sounds like a description of Hillary Clinton. Although she's anything but magnetic.
Even more so if you shorten it to "skyrmbag".
Thanks for clearing that up for us.
It came down the chimney, rolled across the room and nailed him as he slept in bed.
He was burned head to toe.

If I were a physicist, especially a physicist working on skyrmions and antiskyrmions, I would avoid April 1 as a publication date.
You didn’t know that? I would never have owned up to that.
My niece played a Higgs Boson in The Younger Scrolls: Skyrmion MMORPG.
Looks like my Norelco shaver.
Ironically the ranch hand's name was Skyrmion Bags
