报告摘要: Novel phenomena in unstable exotic nuclei, such as quantum phase transition (QPT), shape coexistence, new fission mode, etc. have brought many new physics insights in nuclear physics and, on the theoretical side, challenge established concepts and highlight shortcomings and required modifications to the current nuclear theory. The covariant density functional theory (CDFT) has achieved great success in the description of nuclear structure over almost the whole nuclide chart. However, the collective large-amplitude collective motion related to nuclear shapes and fission can only be studied by including correlations beyond the static mean field. Recently, we have developed the (time-dependent) collective Hamiltonian based on CDFT for the nuclear low-lying spectroscopy and fission dynamics, and applied to some interesting topics: (1)systematic study on shape coexistence and shape phase transitions; (2)Nuclear octupole deformations and parity doublet structure; (3)Nuclear fission of actinides.
