a–c, Fan diagram (upper) and spectra at B = 0 (lower) of the 1.10° (a), 1.16° (b), and 1.18° (c) twisted samples. d Phase diagram of correlated Chern insulators (CCIs, shadowed blue regions) determined from Bc and the critical twist angle at B = 9 T. The CCI boundaries closely correspond to the zero field cascade features (guided by the red curves), highlighting the link between cascade phenomena and CCIs over a broader range detuned from the magic angle.
