We investigate multipartite entanglement dynamics in disordered spin-1/2lattice models exhibiting a transition from integrability to quantum chaos.Borrowing from the recently introduced generalized entanglement framework, weconstruct measures for correlations relative to arbitrary local and bi-localspin observables, and show how they naturally signal the crossover betweendistinct dynamical regimes. In particular, we find that the generation ofglobal entanglement is directly ruled by the local density of states in theshort time limit, whereas the asymptotic amount of entanglement is proportionalto the degree of delocalization of the chaotic many-body state. Our results arerelevant to the stability of quantum information in disordered quantumcomputing hardware.Comment: 4 pages, 4 figure
