Abstract

In this paper, we propose a first principle calculation method for the effective Zeeman's coupling based on the second perturbation theory and apply it to a few topological materials. For Bi and Bi $_2$ Se $_3$ , our numerical results are in good accord with the experimental data; for Na $_3$ Bi, TaN, and ZrTe $_5$ , the structure of the multi-bands Zeeman's couplings are discussed. Especially, we discuss the impact of Zeeman's coupling on the Fermi surface's topology in Na $_3$ Bi in detail.
