- Title
Density-Dependence of Nuclear Symmetry Energy: Role of QCD Chiral Phase Transition.
- Authors
Xia, Yonghui; Xu, Chang; Zong, Hongshi
- Abstract
The density-dependence of symmetry energy is of particular importance to many problems in nuclear physics and astrophysics. By using the functional path integral method, we show explicitly the relation between nuclear symmetry energy and isospin susceptibility. The latter one is found to be a probe to the QCD chiral phase transition. We further found in the Nambu-Jona-Lasinio model calculations that, the nuclear symmetry energy has an abrupt change at the critical nuclear density where the chiral symmetry restores partially.
