Metallic band structure along the high-symmetry path a. Γ-M-K-Γ for the kagome lattice, and b. Γ-M\({}^{\prime}\)-K\({}^{\prime}\)-Γ for the 2 × 2 kagome superlattice, for the tight-binding model with uniform nearest-neighbor hopping (ti,j = −1) and ϵi = 0. The dashed horizontal line indicates the Fermi energy at 5/12 filling. The inset of a shows the hexagonal Brillouin zone of the kagome lattice (in black) together with the location of the high-symmetry points and the chosen path (in red).
