Strong correlations in ABC-stacked trilayer graphene: Moiré is important
Adarsh S. Patri, T. Senthil
Abstract
Recent experiments uncovering ferromagnetism and superconductivity in multilayer graphene have questioned the importance of moir\'e potentials in determining the myriad phenomena in two-dimensional materials. In this work, using Hartree-Fock analysis with a careful treatment of periodic potentials, the authors demonstrate that moir\'e potentials indeed crucially affect the strong correlation physics, with their impact as beyond that of a weak perturbation. In short: moir\'e is important.
