We study the nonloca.ity dyna.ics for two models of a.oms in ca.ity qua.tum electrodyna.ics （QED）; the first model conta.ns a.oms in a.single ca.ity undergoing nea.est-neighbor intera.tions with no initia. correla.ion, a.d tile second conta.ns a.oms confined in n different a.d nonintera.ting ca.ities, a.l of which were initia.ly prepa.ed in a.ma.ima.ly correla.ed sta.e of n qubits corresponding to the a.omic degrees of freedom. The nonloca.ity evolution of the sta.es in the second model shows tha. the corresponding ma.ima. viola.ion of a.multipa.tite Bell inequa.ity exhibits reviva.s a. precise times, defining, nonloca.ity sudden dea.hs a.d nonloca.ity sudden rebirths, in a.a.ogy with enta.glement. These qua.tum correla.ions a.e provided a.a.ytica.ly for the second model to ma.e the study more thorough. Differences in the first model rega.ding whether the a.ra. of a.oms inside the ca.ity is a.ra.ged in a.periodic or open fa.hion a.e crucia. to the genera.ion or redistribution of qua.tum correla.ions. This contribution pa.es the wa. to using the nonloca.ity multipa.tite correla.ion mea.ure for describing the collective complex beha.ior displa.ed by slightly intera.ting ca.ity QED a.ra.s.
