Researchers at the University of Washington have identified a new quasiparticle, the anyon-trion, enabling the optical detection of fractional charges without magnetic fields. Using twisted bilayer MoTe₂, the team observed distinct photoluminescence signatures that confirm the presence of anyons in fractional Chern insulators.

The discovery bridges quantum optics and condensed matter physics, opening new paths toward stable quantum computing and advanced topological materials.
