Fragmented eigenstate thermalization versus robust integrability in long-range models
In fully connected models, integrability remains robust against non-extensive and extensive one-body perturbations but becomes extremely fragile under extensive two-body perturbations, which trigger chaos at infinitesimal strength within symmetry-defined energy bands and produce fragmented eigenstte
