a–e, Point spectra versus gate voltage on an AB site (θ = 1.03°) at B = 4 T (a), B = 5 T (b), B = 6 T (c), B = 7 T (d) and B = 8 T (e). Coloured dashed lines indicate positions calculated with the corresponding Chern numbers. f, Tracking of cascades on the conduction band at different magnetic fields. As the field is increased, the shifting of cascade onsets follows the evolution of Chern insulators. a and e show the same data as Fig. 1d, e; b–d are at intermediate fields on the same area.
