The properties of conventional materials are well described with non-interacting electrons. When electrons are confined in atomically thin sheet (2D), nanowires (1D), or quantum-dot (0D) structures, they are forced to interact with each other.
Moiré quantum materials
One example of low-dimensional quantum materials is van der Waals heterostructures with a moiré potential that naturally forms with a specific twist angle between layers.
