Recent experiments on rhombohedral multilayer graphene (RMG) with a substrate-induced moire potential have identified both Chern insulators and fractional Quantum Hall states at zero magnetic field, whose origin is presently mysterious. The operative degrees of freedom are in the valence band minima, which feature strong correlations and non-trivial quantum geometry. The first part of this talk will study a microscopic model of RMG. I will show that, even without a moire potential, interactions spontaneously break continuous translation symmetry and time-reversal symmetry at the mean-field level to produce an electron crystal with finite Chern number. Such a state is called an anomalous Hall crystal. Many-body numerics at fractional fillings then reveal fractionalized ground states, consistent with experiments. I will also show how metallic Wigner crystals form and naturally explain a puzzling pocket of hole carriers in experiments. The second part of the talk will introduce λ-jellium, a minimal extension of the jellium model whose interaction strength and Berry curvature are independently tunable. I will present evidence that it hosts an anomalous Hall crystal phase that is stable to quantum fluctuations.
