Calculated band structure of CePt₂In₇ along high-symmetry directions of the Brillouin zone (BZ). (a) Calculated results without including spin-orbital-coupling (SOC). (b) Calculated band structure including the SOC. (c) Calculated band structure with the on-site Coulomb repulsion (effective U = 3.0 eV). (d) Calculated band structure with the orbital characteristics marked. The red dots represent the Ce-4f orbitals, the blue dots represent the In-5p orbitals, and the green dots represent the Pt-5d orbitals. The size of the dots represents the related orbital weight. (e) The total and partial density of states corresponding to calculations (a). (f) Bulk Brillouin zone of CePt₂In₇ with high symmetry momentum points marked. The locations of G, X, N, and M points are at plane while the corresponding Z, R, and A points are at plane.
