Description
Lorenzo Graziotto and co-authors published this study in 2026. It shows how a light cavity can steer an electron phase in a chip. The setup holds a sheet of electrons in a strong magnetic field, cooled to near absolute zero. In that state, resistance follows the quantum Hall pattern, with flat steps. Between steps, electrons can line up into stripes, a fragile ordered phase that heat easily disorders.
With the cavity in place, resistance along one direction fell below even its zero-field value. The team reads this as the cavity's vacuum field steadying the stripes. The effect appeared only at the coldest settings and between the Hall steps. The work counts as a first: cavity control over a correlated electron phase, shown through transport rather than light. It hints at tuning materials with empty space itself.
