Ultrashort laser pulses offer a new way to probe electrons' quantum geometry
Researchers from Friedrich Schiller University Jena and the University of Regensburg have used ultrashort laser pulses to measure Berry curvature—a quantum property of electrons—in a single-layer semiconductor, tungsten diselenide. This method could provide new insights into the geometric properties of electron states, potentially advancing our understanding of quantum mechanics.
