Artificial intelligence for artificial materials: moiré atom
share
Moiré engineering in atomically thin van der Waals heterostructures creates artificial quantum materials with designer properties. We solve the many-body problem of interacting electrons confined to a moiré superlattice potential minimum (the moiré atom) using a 2D fermionic neural network. We show that strong Coulomb interactions in combination with the anisotropic moiré potential lead to striking “Wigner molecule" charge density distributions observable with scanning tunneling microscopy.
