Engineering high Chern number insulators

Realizaition of high Chern number insulator is an important issue for potential applications in technologies. As such example, graphene-like honeycomb lattice with long range hopping was proposed for a high Chern number insulator. Furthermore, multilayer quantum anomalous Hall system was also proposed recently and experimentally realized for high Chern number insulators. However, a systematic method to predict such kind of material is still lacking. Here, we propose a practical method to design the model of the two-dimensional Chern insulators with arbitrary high Chern number using controllable one-dimensional Rice-Mele model.
