Researchers have successfully developed an optical method to directly measure Berry curvature in atomically thin tungsten diselenide using ultrashort laser pulses. This breakthrough simplifies the experimental determination of quantum geometric properties that were previously accessible only through complex setups or theoretical models. The technique validates existing theories while opening new avenues for probing electron behavior at the nanoscale.
Quantum geometry of materials mapped with light, researchers say
Researchers at the Universities of Jena and Regensburg are developing an optical technique to investigate the quantum geometry of ultra-thin materials, focusing on Berry curvature—a quantity describing geometric properties of electrons. They measured Berry curvature in a one atomic layer thick layer of tungsten diselenide, using ultrashort laser pulses.

The team used…
