Correlated insulators in twisted bilayer graphene
Ipsita Mandal, Jia Yao, Erich J. Mueller
Abstract
Experiments on graphene bilayers, where the top layer is rotated with respect to the one below, have displayed insulating behavior when the moir\'e bands are partially filled. We calculate the charge distributions in these phases, and estimate the excitation gaps.
