What is Twisted Graphene Bilayers Hamiltonian about?
This document provides a review of graphene Hamiltonians, from monolayer to twisted bilayer graphene. It begins by describing the crystal structure and energy bands of monolayer graphene, and derives its low-energy Hamiltonian near the Dirac points using a tight-binding model. It then discusses the Bernal-stacked bilayer graphene, its tight-binding model, and parabolic energy spectrum near the Dirac point. Finally, it introduces twisted bilayer graphene and the resulting moiré pattern from the twist, but do
