Ultrashort laser pulses offer a new way to probe electrons' quantum geometry
TL;DRScientists use ultrashort lasers to measure Berry curvature, a hidden quantum property of electrons.
Why it matters: Better understanding electron geometry could unlock advances in quantum computing and materials science.
Researchers at Friedrich Schiller University Jena and the University of Regensburg have developed a method for determining, using light, a quantum property of electrons that has hitherto been difficult to access. The focus is on what is known as Berry curvature—a quantity that…
