$Floquet fractional Chern insulators and competing phases in twisted bilayer graphene$

Floquet fractional Chern insulators and competing phases in twisted bilayer graphene

We study the many-body physics in twisted bilayer graphene coupled to periodic driving of a circularly polarized light when electron-electron interactions are taken into account. In the limit of high driving frequency $\Omega$, we use Floquet theory to formulate the system by an effective static Ham...
