Title: Relativistic approaches to nuclei under extremes
Speaker: Dr. Peng-Wei Zhao，Argonne National Laboratory
The development of worldwide rare isotope beam facilities has brought many new insights in nuclear physics. In particular, novel structure in nuclei towards extreme isospin and spin has acquired great interest 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 recent progress in improving and extending the nuclear CDFT, which are 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 within the tilted-axis-cranking approach. It has provided successful description of novel rotation and exotic shape for nuclei towards high isospin and spin. The success of our model stimulates a number of new measurements, and I will present several examples for our interactive research with experimentalists.
About the Speaker:
Dr. Pengwei Zhao received his Ph.D. degree in July 2012 from Peking University (PKU), and then he was awarded the Outstanding Postdoctoral Fellowship at PKU. As a result, he remained at PKU for 2 more years. He went to the Yukawa Institute for Theoretical Physics in Kyoto University as a research assistant professor in 2014, and he is now working at Argonne National Laboratory as a postdoctoral fellow. His research mainly focuses on the extension and applications of covariant density functional theory for nuclear physics towards the extremes of isospin and/or spin. To date, he has 38 papers published in peer-reviewed journals (including 1 review in Frontiers of Physics, 6 Physical Review Letters, 1 Physics Letters B, 21 Physical Review C), which are cited more than 610 times. In addition, he has also contributed 16 conference proceedings.
