Fig. 4: The band calculations.
From: Orbital-selective Dirac fermions and extremely flat bands in frustrated kagome-lattice metal CoSn
a, b DFT calculated bands along high-symmetry directions without and with SOC, respectively. Orbitals characters are indicated by the different colors. Flat bands (FB), Dirac points (DP), and band gaps induced by SOC at the Dirac points are indicated. c DOS from calculation and experiment. Up panel: Calculated total and orbital-resolved DOS of Co 3d narrowed 1.5 times in energy range. Down panel: Integrated EDCs in experiments. d DFT+DMFT calculation with SOC.
