Figure 11. (A) Crystal structure of bulk AFM MnBi2Te4 with high symmetry points in reciprocal space. Band structures profiles (B) without SOC and (c) with SOC. (D) SOC-dependent band gap energy at Γ, showing an evolution from a trivial insulator to a topological insulator by changing the SOC. (E) Wannier charge center evolving with ky, referring to a nonzero topological invariant[189].
