Competing Chern states revealed by quasiparticle charging in moiré rhombohedral graphene

Hongyuan Li, Zuhan Geng, Junseok Seo et al.

Moiré materials realize a versatile platform for exploring the physics of fractional Chern insulators (FCIs). The recently observed evolution from FCIs to an extended quantum anomalous Hall background upon lowering the electronic temperature in moiré rhombohedral graphene (mRG)8 raises a fundamental question: Is it caused by a failure to equilibrate the edge states of an FCI or by a genuine phase transition in the...

Quantum-Geometric Design of Lattice Generalized Landau Levels

Bohao Li, Fengcheng Wu

We design lattice models with tailored quantum geometry, including generalized Landau levels (LLs) satisfying the integrated trace condition and higher Chern bands with ideal quantum geometry. Our models with $N=2$, $3$, and $4$ sublattices include a generalized Haldane model ($N=2$ honeycomb lattice model) with Gaussian decaying hoppings realizable in twisted bilayer MoTe$ 2$, and $N \geq 3$ models with exponenti...
