General features of LnPn band structure. a, b Electronic band structure of CeBi in non-magnetic state a without and b with spin-orbit coupling. The orbital character weights are represented by the size of the circles. The blue circles are Bi-6p orbitals, red circles are Ce-5d t2g orbitals, and green circles are Ce-5d eg orbitals. c Comparison between f-core non-magnetic state CeBi band structure in the folded Brillouin zone (red lines) and LDA + U antiferromagnetic (AFM) state CeBi band structure (blue lines). Notice that in AFM state, the Brillouin zone is folded, so the band structure is more complicated. Nevertheless, the inversion gap is still present and the anti-crossing feature can be identified along Γ–X (red-circled area)
