New quasiparticle discovered in moiré patterns

If you hold one wire mesh on top of another one and look through it, you'll see a larger pattern called a moiré pattern formed by the overlapping grids of the two meshes, which depends on their relative twisted angle. Scientists developing new materials are actively studying moiré patterns in overlapping atomically thin materials—they produce intriguing electronic phenomena that includes unconventional superconductivity and ferromagnetism.
