Topological Order Without Band Topology in Moiré Graphene
Hui Liu, Raul Perea-Causin, Zhao Liu +1
The discovery of zero-field fractional Chern insulators (FCIs) in moiré materials has attracted intense interest in the interplay between topology and correlations. Here, we demon…

Non-Abelian Fractional Chern Insulators and Competing States in Flat Moiré Bands
Hui Liu, Zhao Liu, Emil J. Bergholtz
Breakthrough experiments have recently realized fractional Chern insulators (FCIs) in moiré materials. However, all states observed are Abelian, the possible existence of more exo…

Broken Symmetry in Ideal Chern Bands
Hui Liu, Kang Yang, Ahmed Abouelkomsan +2
Recent observations of the fractional anomalous quantum Hall effect in moiré materials have reignited the interest in fractional Chern insulators (FCIs). The chiral limit in which…
