a Mapping of the first derivative of the Hall resistance Ryx as a function of magnetic field B and filling factor ν. The mapping is converted from the original B–n2D mapping data via ν = n2Dh/eB (see also Supplementary Figs. 4 and 5). Plateau transitions between the quantum Hall states (corresponding to the brighter regions in the mapping) indicate the existence of multiple crossings of the Landau levels. The overlaid dashed lines are guides for eyes. b Schematic illustrations for the external-field-induced splitting of the Weyl nodes of opposite chirality (W±) and consequent degeneracy lifting of the two Weyl orbits. c Fan diagram with complex Landau level crossings simulated by introducing an effective Zeeman splitting, and a relative energy shift between the two Weyl orbits (see Supplementary Note 5).
