Kivonat: 




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 40 Mg, 42 Si and 44 S.
