【学术报告】Pengwei Zhao ---Relativistic description of nuclear spectroscopy: explanations and

      The development of worldwide rare isotope beam facilities has brought many new insights in nuclear physics. In particular, the nuclear  spectroscopic properties, which reveal rich structure information of atomic nuclei, has acquired great interests over the years for the challenges and implications it involves. Theoretically, covariant density functional theory (CDFT) has achieved great success in describing many nuclear phenomena over the past several decades. In this talk, I will highlight the recent progress  in improving and extending the nuclear CDFT, which is motivated by experimental results on both nuclear ground and excited states. We developed a new covariant functional PC-PK1, which considerably improves the isospin dependence of nuclear properties, and is more reliable for the description of neutron-rich nuclei. We also extended CDFT for nuclear spectroscopic properties at a rotating mean-field level. It has provided successful description of novel rotation and exotic shape for nuclei towards high isospin and spin. Finally, I will also introduce our recent efforts for developing a microscopic energy density functional.
