In twisted MoTe2, a uniform Chern-Simons flux approximation predicts Jain-sequence fractional Chern insulators plus higher-Chern 'fractal' fractional Chern insulators, with electric fields able to close gaps and trigger topological transitions.
In this case, νCF = 1 2 + Z, corresponding to a half-filled CF band
