By reducing the many-body problem formulated in terms of N-body wave functions to the one-body level with the density distributions, the density functional theory (DFT) has been enormously popular. However, the quality of the DFT results crucially depends on the accuracy of the energy density...

The shell structure and magic numbers are fundamental properties of atomic nuclei, which predict the existence of the island of stability for superheavy nuclei. On one hand, the occurrence of nuclear magic numbers can be theoretically explained by introducing a spin-orbit interaction between nucleons, leading to a breaking of the relevant spin symmetry. On the other hand, the observation of...
