At the Heart of Quantum Matter: Geometry

Researchers from the University of Geneva, the University of Salerno and CNR‑SPIN have directly detected the quantum metric—a geometric property of electron wavefunctions—at the interface of strontium titanate and lanthanum aluminate, as reported in Science (Aug 2025). The quantum metric, previously only a theoretical construct, was shown to bend electron trajectories under strong magnetic fields, analogous to how gravity bends light. This observation confirms that quantum geometry is an intrinsic feature of many quantum materials. The work opens pathways for designing terahertz‑frequency electronics, superconductors and advanced light‑matter devices.
