“…[39], the DRHBc theory with the pointcoupling density functionals was developed for eveneven nuclei. It has recently been applied to construct a mass table for even-even nuclei [40], and the mass table for odd-A and odd-odd nuclei is under construction [41]. In addition, many interesting studies have been performed, such as the impact of deformation effects on the location of the neutron drip line [42], the dynamical correlation energy with a two-dimensional collective Hamiltonian [43], the multipole expansion of densities [44], the rotational mode of deformed halo nuclei [45,46], the bubble structure and shape coexistence [47,48], the peninsulas of stability beyond the two-neutron drip line [49−51], the optimization of the Dirac Woods-Saxon (WS) basis [52], the shell closure at in the neodymium isotopic chain [39,41], the collapse of the shell closure in the newly discovered [37], the oddeven staggering and kink structures of charge radii of isotopes [53], the prolate-shape dominance in atomic nuclei [54], the nuclear charge radii and shape evolution of Kr and Sr isotopes [55], and the one-proton emission of Lu using the DRHBc+WKB approach [56].…”

Magicity, or shell closure, plays an important role in our understanding of complex nuclear phenomena. In this work, we employ one of the state-of-the-art density functional theories, the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) with the density functional PC-PK1, to investigate the evolution of the $N=20,28,50$ shell closures inthe $ 20 \leqslant Z \leqslant 30$ region. We show how these three conventional shell closures evolve from the proton drip line to the neutron drip line by studying the charge radii, two-neutron separation energies, two-neutron gaps, quadrupole deformations, and single-particle levels. In particular, we find that in the $ 21 \leqslant Z \leqslant 27$ region, the $N=50$ shell closure disappears or becomes quenched, mainly due to the deformation effects. Similarly, both experimental data and theoretical predictions indicate that the $N=28$ shell closure disappears in the Mn isotopic chain, also predominantly due to the deformation effects. The DRHBc theory predicts the existence of the $N=20$ shell closure in the Ca, Sc, and Ti isotopic chains, but the existing data for the Ti isotopes suggests the contrary, and therefore more investigations are needed.

“…By 2016, a global search for octupole deformation was performed using covariant density functional theory [26]. Researchers used five of the most recent covariant energy density functionals, DD-PC1 [27], NL3* [28], DD-ME2 [29], PC-PK1 [30], and DD-MEδ [31], with separable pairing interaction (TMR) [32,33] to study the octupole deformation in the ground states of even-even nuclei. According to their conclusion, DD-ME2 with TMR pairing interaction can correctly predict the islands of octupole deformation and is in general agreement with the available experimental data.…”

In this paper we have systematically analyzed the ground state of uranium isotopes from 225 to 240. In our calculations, we used the covariant energy density functional of density dependent meson exchange interaction (DD-ME2) with separable pairing interaction (TMR). Using the multiple deformation constraint, we calculate the potential energy surface (PES) of the uranium isotopes forboth even-even and even-odd nuclei with quadrupole and octupole deformation. By comparison with experimental data and Hartree-Fock-Bogoliubov calculations with Gogny D1S, the ground state of the uranium isotopes is always preferred to reflection-asymmetric deformation with our calculation.
