ProgrammeP.24 -- Poster, ANSWCCMS-2023 Date: Tuesday, 7 November 2023 Time: 13:00 - 14:30 Competing Laughlin state and Wigner crystal in Bernal-stacked bilayer grapheneNgoc Duc Le and Thierry Jolicoeur Université Paris-Saclay, CNRS, CEA, Institut de Physique Théorique, 91190 Gif-sur-Yvette, France In Bernal-stacked bilayer graphene, the two Landau levels N = 0 and N = 1 are quasi-degenerate. Their energy difference can be tuned by varying the electric voltage across the two layers. By neglecting the mixing with all other Landau levels, this situation is reminiscent of an extreme Landau level mixing, which favors the formation the Wigner crystal state of matter. In this work, we study the competition between the Laughlin state and Wigner crystal at filling factor $\nu = 1/3$ of Bernal-stacked bilayer graphene. Our results show the possibility of electrically inducing the Wigner crystal and open perspectives to study this state of matter in Bernal-stacked bilayer graphene.
