Rare quantum state reveals particles with quarter-electron charge

Дата публикации: 25-09-2026 13:00:08

An electron's charge is normally fixed, like a coin you can't break into pieces. But if electrons are cooled close to absolute zero and trapped in a two-dimensional layer under a powerful magnetic field, they organize into a collective state of "quasiparticles" that seem to hold only a fraction of an electron's charge.
