In the core-particle coupling scheme, a collective model is proposed to describe high-spin phenomena in the triaxial odd-A and odd-odd systems with their even-even cores assumed to follow a critical point symmetry. It is shown that the model Hamiltonian can be approximately solved with the solutions being expressed in terms of the Bessel functions of irrational orders, which in turn generate a...
The relativistic configuration-interaction density functional theory, which combines the advantages of configuration-interaction shell model and relativistic density functional theory and allows to treat nuclear spectroscopic properties in the laboratory frame, is applied to investigate the chiral rotation in $^{130}$Cs. Both energy spectra and transition probabilities of the chiral doublets...
Following the reports of candidate chiral doublet bands observed in cesium isotopes, the possible chiral candidates and the evolution of three-dimensional rotation in $^{120-134}{\textrm{Cs}}$ are investigated within the microscopic three-dimensional tilted axis cranking covariant density functional theory (3DTAC-CDFT). By investigating the evolution of the polar angle $\theta$ and azimuth...
Based on covariant density functional theory, the pairing correlations are studied with the shell-model-like approach (SLAP), in which the particle numbers are conserved strictly, and the blocking effect is handled precisely.
The temperature-dependent S-shaped heat capacity curve was obtained for even-even nuclei, which predicts the occurrence of the pairing phase transition near the...
Results from recent experiments studying nuclei in the $^{78}$Ni region suggest that the N = 50 shell closure persists, in agreement with state-of-the-art shell model calculations. However, how collectivity manifests and evolves in this region of the Segrè chart is still an open question, particularly concerning phenomena such as vibrational modes, triaxiality and shape coexistence. This is...
