Fig. 4

a–c Mass term m (form factor Is) shows no zero crossing (no dip), one zero crossings (one dip) and two zero crossings (two dips) in the quantum limit for normal insulator, weak TI and strong TI, respectively. d Color map of critical magnetic fields, \({\mu }_{0}{H}_{B2}^{c}\), versus coefficients Mx and M⊥ of a typical strong TI k ⋅ p model. Here M0 is fixed to be -0.036 eV, while the dashed red line indicates the fitted value of M⊥ based on band structure. e With considering the Zeeman effect, \({\mu }_{0}{H}_{B2}^{c}\) locates in a range, indicated by pink thick curve, which is consistent with our experimental values.
