Research paperTheoreticalComputational Ketic ModelNematic and partially polarized phases in rhombohedral graphene with varying number of layers: An extensive Hartree-Fock StudyGuillermo Parra-Martínez, Alejandro Jimeno-Pozo, Jose Angel Silva-Guillén, Francisco GuineaarXiv·2025·10.48550/arxiv.2405.16944·arXiv:2508.00986AbstractSystematic Hartree-Fock calculations are used to map the phase diagram of rhombohedral (ABC-stacked) graphene as a function of layer number, carrier density, displacement field, dielectric screening, and Ising spin-orbit coupling. The study finds cascades of isospin-polarized and partially polarized metallic phases, including nematic states that break C₃ symmetry, across multilayer graphene from bilayer to heptalayer and persisting beyond 20 layers. The results show systematic shifts of symmetry-broken regions with increasing layer number and demonstrate that reduced dielectric screening and proximate Ising SOC reshape the correlated phase diagram.Read more
