Particle accelerators have learned to preserve the vortex motion of electrons despite random jolts.

In a ring accelerator, a beam of electrons circles millions of times. If the electrons are twisted like strands in a rope, their vortex motion should persist. But along the way, random jolts from imperfect magnets can disturb them.

Scientists have described how vortex motion changes under such perturbations. It turns out that even with random jolts, there is a special combination that remains nearly unchanged. It's like a spinning top: if you give it a gentle nudge, it may wobble, but its axis of rotation stays the same.

For the IOTA accelerator, vortex motion is preserved over 200,000 turns, and for PETRA III, over 2 million turns.

This stability paves the way for using vortex beams in precision experiments where not only the particle's energy but also its rotation matters.

Vortex electrons carry 'orbital angular momentum,' like a planet orbiting a star, and this momentum can be used as an additional channel for information transfer.

In the TV series 'Stargate,' teleportation devices use vortex-like streams of particles, similar to those described in the article.
