Abstract: While the van der Waals interaction in layered crystals is weak, there is hybridization that gives rise to a superlattice potential as a function of the rotation in twisted heterostructures. The long-range modulation of this potential results in both commensurate and incommensurate structures, involving tens of thousands of atoms in a single moiré supercell. This poses significant challenges to conventional methods for studying the electronic properties of these materials. In this talk, I will present new approaches to accessing the quantum transport properties of twisted heterostructures, specifically applied to twisted bilayer graphene.
