Research paperTheoreticalCharge-density waves and stripes in quarter metals of graphene heterostructuresSk Asrap Murshed, Bitan RoyarXiv·2025·10.1103/png3-tym5·arXiv:2510.20816AbstractMotivated by recent experiments, the paper identifies valley-coherent charge-density wave order in the non-degenerate quarter-metal of chirally stacked n-layer graphene, spanning monolayer, Bernal bilayer, and rhombohedral multilayer graphene. It argues that the charge-density wave breaks translational symmetry and, for even layer number, C₃ rotational symmetry to produce stripe order, while preserving C₃ for odd layer number. The work also analyzes how layer polarization, antiferromagnetism, and anomalous Hall order lift degeneracies under perpendicular displacement fields, yielding metal, half-metal, and quarter-metal regimes.Read more
