ABSTRACT: When layers of two-dimensional materials are placed on top of one another with a relative twist angle, they generate a beautiful interference pattern known as a moiré superlattice. The interface between the layers is highly sensitive to the twist angle and external perturbations, making twistronics (from "twist" & "electronics") among the most controllable platforms for studying fermions in two-dimensions. When the angle is sufficiently small, the electrons undergo severe band flattening which encourages the appearance of superconductivity, strongly correlated phases, and topological insulators.
