报告内容摘要：Three-nucleon force and continuum play important roles in reproducing the properties of atomic nuclei around driplines. In this work, we have developed the chiral three-nucleon force within the continuum Berggren representation. Bound, resonant and continuum states are treated on equal footing in the complex-momentum Berggren space. We choose neutron-rich oxygen isotopes as the test ground. The oxygen isotopes have been well studied experimentally, with the neutron dripline determined. Recent experiments have gone beyond the neutron dripline of the oxygen chain. The calculations were performed with the Gamow shell model, well reproducing the properties of oxygen isotopes around the neutron dripline. The chiral three-nucleon force was dissected by analyzing the contributions of the 2π exchange,1π exchange and contact terms.

个人简介：He is currently studying at the School of Physics, Peking University, under the instruction of Prof. Xu Furong. During his Ph.D., he devoted himself on the study of chiral effective three-body forces and advanced quantum multi-body methods for the firstprinciples calculation of atomic nucleus. Since 2016, he has cooperation with the Italian INFN Institute, and up to now, he has published four articles on PRC. He has participated in international conferences many times and gave a presentation during the International Workshop on Many-body System with Strong Interactions conference. He has won several kinds of honors such as the Peking University President Scholarship, Outstanding Student, and Outstanding Research Award.
