Physicists Measure Quasiparticle With Quarter Electron Charge

Original: Physicists Just Measured a Quasiparticle With One-Quarter of an Electron’s Charge

Physicists report measuring a quasiparticle carrying exactly one-quarter of an electron's charge, a fractional value that challenges the usual picture of electric charge as indivisible in ordinary materials. Such fractional quasiparticles are of keen interest in condensed matter physics, where they emerge from collective electron behaviour and are studied for potential use in topological quantum computing. The finding is drawing attention across the physics community.

Why now: Fractional charge measurements are rare and touch on exotic quantum states that could matter for future quantum technologies.
