DESCRIPTION:Speakers: Yibin Qian（钱以斌） (Nanjing University of Sci
 ence and Technology)\n\nAbstract:\nCluster phenomena widely exist at vario
 us physical levels\, from galaxy clusters with filamentary structure at th
 e largest scale to quark clusters confined in hadrons at the smallest scal
 e. The cluster degrees of freedom inside atomic nuclei are also one of the
  key factors determining nuclear structure properties and dynamical behavi
 or. In recent years\, research on cluster structure and cluster phenomena 
 in the light nuclear region has made new progress both experimentally and 
 theoretically\, while as the number of nucleons in a nucleus increases\, n
 ucleon-nucleon correlations become more complex and lead to an explosive g
 rowth in the dimension of the configuration space. How cluster formation a
 nd correlations in heavy nuclei and even superheavy nuclei affect their st
 ructural properties and reaction mechanisms has naturally become a difficu
 lt problem\, posing new challenges to experimental observations and existi
 ng nuclear theories.In recent years\, we have conducted a series of theore
 tical studies on how cluster physics influences the structural properties 
 and decay properties of heavier nuclei. This report mainly covers two aspe
 cts: first\, starting from the extreme two-body cluster model\, gradually 
 constructing a heavy-nucleus cluster model that includes core excitation a
 nd cluster-state coupling\, and trending toward establishing a complete mi
 croscopic structure model with cluster degrees of freedom\; second\, the s
 tudy of long-lived nucleus alpha decay and early solar system evolution\, 
 as well as research progress on 2α decay in nuclei.\nBiography:\nQian Yib
 in\, a professor at School of Physics in Nanjing University of Science and
  Technology. After receiving the Ph.D. from the School of Physics\, Nanjin
 g University in 2014\, he joined Nanjing University of Science and Technol
 ogy. From 2017 to 2018\, he was a visiting postdoctoral researcher at KTH 
 Royal Institute of Technology\, Sweden. He is mainly engaged in theoretica
 l nuclear physics research\, focusing on nuclear cluster structure and dec
 ay\, fundamental properties of nuclei\, and symmetry energy constraints. H
 e has published more than 70 papers in academic journals such as PRL/C and
  PLB\, with more than 1\,400 citations. He was a recipient of the Jiangsu 
 Province Excellent Young Scientists Fund (2019) and was selected for the J
 iangsu Province "333" Talent Project (2022).\nHost: Prof. Yu-Min Zhao\nAlt
