Fig. 3. Landau fan diagrams and spontaneous flavor polarization at the high field for D > 0.

Landau fan diagrams in device D1 at (a, c) D = 0.66 V/nm, (d, f) D = 0.52 V/nm, (g, i) D = 0.47 V/nm, and (j, l) D = 0.39 V/nm, all acquired below T = 0.3 K. The leftmost column shows ρ_xx, the central column shows ρ_xy, and the rightmost column schematically denotes the strongest observed gapped states. In the schematic, purple lines correspond to states tracing to ν = 0, blue to ν = 1, green to ν = 2, orange to ν = 3, and yellow to ν = 4. The vertical black lines denote topologically trivial insulating states. Selected states are labeled by their respective (t, s) indices.
