Dirac-Brueckner-Hartree-Fock模型中核和中子物质单粒子性质的温度依赖性

Temperature dependence of single-particle properties in nuclear and neutron matter in the Dirac-Brueckner-Hartree-Fock model

Francesca Sammarruca

摘要:

了解核子在非零温度下与富中子物质的相互作用,对于从重离子碰撞到核天体物理的各种应用都是重要的。本文应用Dirac-Brueckner-Hartree-Fock方法和Bonn B核子-核子势,计算了有限温度下对称核物质和纯中子物质的单粒子性质。据发现,温度的影响一般很小,但可以在低密度和动量显着。

英文摘要:

The understanding of the interaction of nucleons in nuclear and neutron-rich matter at non-zero temperature is important for a variety of applications ranging from heavy-ion collisions to nuclear astrophysics. In this paper we apply the Dirac-Brueckner-Hartree-Fock method along with the Bonn B nucleon-nucleon potential to predict single-particle properties in symmetric nuclear matter and pure neutron matter at finite temperature. It is found that temperature effects are generally small but can be significant at low density and momentum.
