Fig. 3

a–c Non-spin-polarized band structure of SMAS displays the orbital contribution of Mn Bg (blue), \({A}_{{{{{{{{\rm{g}}}}}}}}}^{{{{{{{{\rm{out}}}}}}}}}\) (green), and \({A}_{{{{{{{{\rm{g}}}}}}}}}^{{{{{{{{\rm{in}}}}}}}}}\) (red) orbitals along the high symmetry paths M-K-Γ-A-H-L, and d PDOS obtained using LDA functional in DFT. e–g Corresponding orbitally-resolved momentum- and frequency-dependent spectra and, h momentum-integrated spectral function from LDA+DMFT calculation for (U, JH)=(6, 0.8) eV at 210 K with full Coulomb interaction. i Full DFT bands (black) and Wannier interpolated Bg-bands (violet). j Orbital texture with Bg character from constructed Wannier molecular orbitals of non-correlated electronic structure. The inset in a depicts the hexagonal Brillouin zone and spacial k-points therein.
