Gravity-like quantum geometry steers electrons, hinting at faster electronics
Researchers at the University of Geneva and collaborators observed the quantum metric—a hidden geometric feature at the SrTiO3/LaAlO3 oxide interface—that distorts electron trajectories under strong magnetic fields, bending them like gravity bends light. This experimental confirmation of a long-theorized quantum geometry could improve understanding of material properties and enable faster, more efficient electronics and advances in quantum technologies, including terahertz devices and superconductivity.
