Two layers of electrons can be twisted into a quasicrystal pattern that only exists because of the constant vibration of quantum noise.
Quasicrystals are weird structures that are ordered but never repeat, which usually requires very specific atomic arrangements. This new quantum version forms between two layers of electrons that are twisted by exactly thirty degrees. Classical physics would predict this state to be unstable and messy, but quantum zero-point motion actually locks it into place. This quantum noise acts as the glue that stabilizes a complex geometric order that would otherwise vanish. It proves that the inherent uncertainty of the quantum world can actually be a constructive force for creating new matter. This discovery could lead to entirely new classes of electronic materials.

The strongly correlated phases of the homogeneous electron gas constitute the vocabulary of many-body condensed matter physics and find a natural realization in semiconductors. In this setting, recent neural-network variational Monte Carlo calculations discovered an unexpected quantum phase of matter in wide quantum wells: an electronic quasicrystal formed by a bilayer Wigner crystals with a 30-degrees twist. This state defies classical expectations and emerges in a regime dominated by quantum f
