In this presentation, Xinle Shang will give an introduction of short-range correlation (SRC) and the effects on the properties of nuclear matter. SRC, going beyond the traditional independent particle model approximation, describing the short-range behaviours of two nucleons, and playing a significant role in nuclear structure, heavy-ion reaction, and nuclear astrophysics, are an important frontier of nuclear physics. Utilizing the extended microscopic Bruecker-Hartree-Fock (BHF) method, the SRC properties in nuclear matter can be obtained. Using these properties of SRC, especially the quasi-particle strength at Fermi surface, the effects of SRC on the superfluidity, transport coefficient are investigated.
In the second part, Qi Yuan will present our recent ab-initio studies on the exotic nuclei. A primary focus in nuclear structure physics is the investigation of the shell structure and collective properties of nuclei far from stability. Utilizing ab initio valence-space in-medium similarity renormalization group calculations, we have delved into the study of neutron-rich nuclei surrounding N = 28. The results from our ab initio calculations align well with available experimental data, particularly collectivity in the vicinity of 40Mg, 42Si and 44S.
