説明:

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.
