## Description

- description: The topology of the electronic band structure of solids can be described
    by its Berry curvature distribution across the Brillouin zone. We theoretically
    introduce and experimentally demonstrate a general methodology based on the measurement
    of energy- and momentum-resolved optical transition rates, allowing to reveal
    signatures of Berry curvature texture in reciprocal space. By performing time-
    and angle-resolved photoemission spectroscopy of atomically thin WSe become an
    asset in extracting the quantum geometrical properties of solids. We also investigate
    the resilience of our measurement protocol against ultrafast scattering processes
    following direct chiroptical transitions.
