Report Abstract: High-precision experiments in nuclear physics have significantly advanced our understanding of atomic nucleus properties, and some predictions made by nuclear theory are being confirmed by a new generation of high-precision experiments. In this report, we will introduce the theoretical predictions related to nucleon-nucleon short-range correlations caused by tensor interactions, as well as new experimental progress in bremsstrahlung photon production in heavy ion collision reactions. We will also present the theoretical research progress on four-nucleon correlations on the surface of heavy nuclei and the experimental measurements of ideal atomic nucleus cluster decays. Additionally, we will introduce some theoretical predictions in open quantum systems involving the interaction between nuclei and their external environments.
Introduction to the presenter: Xu Chang, a professor at Nanjing University, serves as a doctoral supervisor and the vice dean of the School of Physics. He holds positions as an executive director of the Chinese Nuclear Physics Society, a deputy director of the Physics Teaching Committee of the Chinese Physical Society, a director of the Particle-Nucleus-Cosmology Specialty Committee of the Jiangsu Provincial Physical Society, and is a recipient of the National Science Fund for Distinguished Young Scholars. His primary research interests lie in the theoretical investigation of atomic nuclear quantum many-body systems and exotic quantum phenomena, encompassing the properties of superheavy elements and new nuclides, nuclear clustering and decay mechanisms, nuclear equation of state, medium-energy heavy ion reactions, and exotic quantum phenomena.
