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.

Researchers at the Max Planck Institute and Rice University have mapped 9,000 materials for their quantum states, creating a large-scale reference dataset for the field.
