Author(s): Xin Lu, Yuanfan Yang, Zhongqing Guo, and Jianpeng Liu Moiré superlattices host a rich variety of correlated topological states, including interaction-driven integers and fractional Chern insulators. A common approach to study interacting ground states at integer fillings is the Hartree-Fock mean-field method. However, this method neglects dynamical cor… [Phys. Rev.
