2020年6月19日星期五下午,米兰大学申时行博士在腾讯会议平台,作了题为Nuclear energy density functional with the guidance of ab initio calculation 的线上学术报告。报告会由兰州大学牛一斐教授主持。
Density functional theory is one of the most important tools in the study of nuclear many-body system. It can give a good description to the nuclear ground and excited states in a large range of the nuclear chart. Yet there are still many open questions concerning how to build a better nuclear energy density functional. With recent advances in ab initio calculations, some hints may be given. In this talk, I will introduce recenet development of one ab initio framework, the relativistic Brueckner-Hartree-Fock theory, in the finite nuclear system. I will show how such ab initio calculation can be used as a guidance to the development of nuclear energy density functional, and how the new functional performs in describing nuclear properties (with special emphasis on the property of nuclear giant resonances).
