Description
We investigate the evolution of nuclear shell structure in neutron-rich isotopes through the lens of quantum information theory, using quantum entanglement entropy as a diagnostic tool. Employing shell model calculations, we compute both single-orbital and total correlation entropy for oxygen and calcium isotopic chains. Our results identify the emergence of new magic numbers at ( N=14, 16 ) in oxygen and ( N=32, 34 ) in calcium, evidenced by pronounced minima in total entropy. The single-orbital entropy further reveals orbital-level decoupling at these closures, confirming enhanced nuclear stability. Extending the analysis to iron, chromium, and nickel isotopes, we explore entanglement patterns near the merging regions of the islands of inversion around ( N=40 ) and ( N=50 ), highlighting collective effects. This study demonstrates that quantum entanglement measures provide a powerful, complementary perspective to conventional observables in tracing shell evolution and uncovering underlying correlations in exotic nuclei.
