Theory of van der Waals materials from interband coherence to moiré butterflies
Abstract: The advent of two-dimensional van der Waals materials brought with it the remarkable potential to realize tunable correlated phases of matter. Here, we delve into the rich physics of these materials, focusing on platforms based on graphene and transition metal dichalcogenides, which have undergone significant progress in recent years. The main themes include interband coherence, moiré physics, and electrostatics. Starting with an overview of the physics of van der Waals materials, we will present the results obtained, including signatures of interband coherence in scanning tunneling microscopy, effects of disorder on interband coherence in twisted bilayer graphene, as well as Hofstadter butterflies for twisted bilayer transition metal dichalcogenides.
