Fig. 1: Crystal and electronic structures for CsCr₃Sb₅ at 5 GPa.

a Crystal structure for CsCr₃Sb₅. b Top view of the kagome Cr-lattice. The local coordinates and atomic d orbitals are also shown for different Cr-sublattices. c Band structures and projected density of states for CsCr₃Sb₅. d The first Brillouin zone and high-symmetry lines for hexagonal CsCr₃Sb₅ lattice. e Fermi surfaces for CsCr₃Sb₅, plotted with FermiSurfer program⁵². The orbital contributions of Cr-d_yz, Cr-d_xz, and Cr-\({d}_{{x}^{2}-{y}^{2}}\) in c, e are denoted by red, green, and blue color components, respectively. The crystal structures are constructed with the VESTA program⁵³.
