Abstract：Recent investigations have established lightly-doped rhombohedral multilayer graphene as an exceptional material for probing electronic phases that arise from strong Coulomb interactions and non-trivial band topologies. This talk will discuss advancements in experimental techniques that have deepened our understanding of electronic behaviors in these systems. We adopt a generalized electron gas model to study the interaction effects in these systems. We present a self-consistent mean-field phase diagram and use time-dependent mean field theory to study their spin-valley paramagnon/ferromagnon excitations. A special focus will be given to unconventional orbital magnetism in the so-called quarter-metal phase. This talk is based on the review article available at arXiv:2408.15884.2024-8
