Maximally Localized Wannier Orbitals and the Extended Hubbard Model for Twisted Bilayer Graphene
We develop an effective extended Hubbard model to describe the low-energy electronic properties of the twisted bilayer graphene. By using the Bloch states in the effective continuum model and with the aid of the maximally localized algorithm, we construct the Wannier orbitals and obtain an effective...
