Scientists Have Summoned a Massless Demon Particle

Physicists from the University of Illinois have successfully summoned a "demon" particle, which stands for "distinct electron motion" with the suffix "-on" added.

The "demon" is a plasmon, a discrete wave rippling through plasma electrons, that is massless and has a neutral charge, as theorized by physicist David Pines in 1956.

The "demon," in this case, actually stands for "distinct electron motion" with the physics favorite suffix "-on" added for good measure.

A paper published by scientists at the University of Illinois showcases how they stumbled upon this demon plasmon by accident, which will help unlock the inner workings of superconductors.
