Abstract

In this study, we present multipartite entanglement results for the Ca and Ti isotopic chains obtained from nuclear shell-model wavefunctions. Our investigation focuses on the first excited 2+1 states, which exhibit signatures of shell closures at N=28 and N=32. We calculate the 4- and 6-tangles, together with their corresponding network representations, providing a detailed picture of the underlying many-body correlations among nucleons. The primary objective of this work is to investigate the influence of shell closures on higher-order n-tangles, thereby gaining insight into the evolution of multipartite entanglement in medium-mass nuclei.
