Scientists just found a hidden quantum geometry that warps electrons

Researchers from the University of Geneva have discovered a previously theoretical "quantum metric" geometry that distorts electron trajectories similar to gravity bending light. By observing this effect at the interface of two oxides under magnetic fields, they've proven this geometry exists in quantum materials and is an intrinsic property of many substances. This breakthrough enhances our understanding of quantum materials and could advance technologies including terahertz electronics, superconductivity, and light-matter interactions.
