University of Illinois Team Finds Wigner Crystal—Not Mott Insulator—in 'Magic-angle' Graphene
Researchers at the University of Illinois at Urbana-Champaign have recently shown that the insulating behavior reported by the MIT team has been misattributed. Professor Philip Phillips, a noted expert in the physics of Mott insulators, says a careful review of the MIT experimental data by his team revealed that the insulating behavior of the “magic-angle” graphene is not Mott insulation, but something even more profound—a Wigner crystal.
