    "abstract": "We investigate multipartite entanglement dynamics in disordered spin-1/2\nlattice models exhibiting a transition from integrability to quantum chaos.\nBorrowing from the recently introduced generalized entanglement framework, we\nconstruct measures for correlations relative to arbitrary local and bi-local\nspin observables, and show how they naturally signal the crossover between\ndistinct dynamical regimes. In particular, we find that the generation of\nglobal entanglement is directly ruled by the local density of states in the\nshort time limit, whereas the asymptotic amount of entanglement is proportional\nto the degree of delocalization of the chaotic many-body state. Our results are\nrelevant to the stability of quantum information in disordered quantum\ncomputing hardware.",
