The electronic structure of rhombohedral multilayer graphene (RMG) undergoes a thickness-dependent topological phase transition, evolving from a 3D generalization of the Su-Schrieffer-Heeger (SSH) model in thin layers to a topological Dirac nodal spiral semimetal (DNSS) in the bulk limit, as revealed by NanoARPES measurements.
This study investigates the effectiveness of spread complexity, a measure of quantum chaos, in characterizing non-Hermitian many-body localization transitions, revealing its ability to distinguish between ergodic and localized phases and detect complex-real eigenvalue transitions.
