Researchers in Konstanz discovered a way to manipulate materials with light by exciting magnon pairs, reshaping their magnetic “fingerprint.” This allows non-thermal control of magnetic states and data transmission at terahertz speeds. Using simple haematite crystals, the technique could enable room-temperature quantum effects. The breakthrough blurs the line between physics and magic.
