Research paperExperimental CharacterizationTheoreticalHeavy Fermion Phase Diagram in Magic-angle Twisted Trilayer GrapheneLe Zhang, Wenqiang Zhou, Xinjie Fang, Zhen Zhan et al.arXiv·2026·10.1103/zzks-vkl2·arXiv:2507.12254AbstractWe demonstrate an electrically tunable heavy fermion phase diagram in magic-angle twisted trilayer graphene by controlling Kondo hybridization between localized flat-band electrons and itinerant Dirac electrons via a displacement field. The results reveal a continuous quantum phase transition from an antiferromagnetic semimetal to a paramagnetic heavy fermion metal, with effective mass divergence and Fermi surface reconstruction at the quantum critical point.Read more
