Abstract:
Chiral effective field theory provides an approach to derive nuclear force from first principles. The resulting chiral nuclear forces have been extensively used in ab initio calculations to study the properties of light and medium-mass nuclei as well as infinite nuclear matter. However, it is still a challenge to use chiral nuclear forces for studying more complicated nuclear systems such as heavy nuclei and neutron stars. We therefore construct a new Skyrme interaction by fitting the equation of state and nucleon effective masses in asymmetric nuclear matter from chiral two- and three-body forces as well as the binding energies of finite nuclei. The obtained Skyrme force can well reproduce both the ground-state properties and the isovector giant dipole resonance of finite nuclei. We further develop a Boltzmann-Uehling-Uhlenbeck transport model based on the new Skyrme interaction and employ it to study pion production in intermediate energy heavy-ion collisions.
About the speaker:
Dr. ZHANG Zhen, associate professor at IFCEN, received his Ph.D. degree in Shanghai Jiao Tong University in 2015, did postdoctoral research in Texas A&M University until he joined IFCEN in July, 2018. His research is focused on the equation of state and symmetry energy of nuclear matter, medium and low energy heavy ion collisions.
