Recently, scientists created a stir in the field of condensed matter physics when they showed that two sheets of graphene twisted at specific angles display two emergent phases of matter. After a careful review of the experimental data researchers say that the insulating behavior of the ''magic-angle'' graphene is not Mott insulation, but something even more profound — a Wigner crystal.
