报告摘要：

　　The phase diagram of multilayer graphene stacks has become a very active research topic in recent times. These systems show a complex behavior, including apparently incompatible features, like superconductivity and magnetism. These multilayers also provide a route to very flat electronic bands, alternative to the ones already observed in twisted stacks. Recent experimental and theoretical research on rhombohedral graphene stacks will be presented, with emphasis on novel phases and anomalous behavior not commonly found in other systems.
