Electrons in Moiré Crystals Explore Higher-dimensional Quantum Worlds

Department of Physics

MIT physicists have discovered 3D “moiré crystals” that simulate four-dimensional quantum materials to a T.

Hundreds of parallel lines comprised of spheres recede into the distance. In the middle ground are seven large red dots and a white 3D arrow pointing up.

When metals are placed in magnetic fields, their electrons orbit at speeds and in shapes related to the metal’s atomic lattice. MIT researchers have discovered “moiré crystals” with two different competing atomic lattices, which together generate a moiré superlattice that is mathematically equivalent to an emergent 4D “superspace” lattice. Researchers have now discovered that some of the electronic properties of moiré crystals simulate those of previously hypothesized 4D quantum materials.
