## Description

- description: We investigated the Fermi surface (FS) in the paramagnetic state of
    Kagome metal CsCr3Sb5 by employing a laser photoemission microscopy. We found
    a circular FS and two hexagonal FSs around the Brillouin zone (BZ) center. Polarization-dependent
    measurements further enable us to detect small FS pockets at the BZ boundary.
    The orbital characters of these FSs were determined by comparing their shape and
    orientations, as well as the band dispersions around the Fermi level, with the
    density functional theory (DFT) calculations. We found that the size of the FS
    is strongly modified from the DFT calculations, suggesting the orbital-dependent
    correlation effect. These results provide an electronic basis for exploring the
    interplay of antiferromagnetic/charge density wave order and possible unconventional
    superconductivity in this compound.
