中子滴的精确交换密度泛函理论

Exact-exchange density functional theory for neutron drops

Joaquín E. Drut, Lucas Platter

摘要:

我们计算的基态性质的有限系统的中子在一个外部的谐波陷阱,通过明尼苏达势相互作用,使用“精确交换”形式的轨道相关的密度泛函理论。我们比较我们的结果与Hartree-Fock计算,发现非常接近的协议。在研究的相互作用的背景下,我们得出结论,这个简单的轨道相关的功能带来了传统的核密度泛函理论的水平Hartree-Fock从头算的方式。我们的工作是基于现实的核子-核子相互作用的高阶从头算核泛函的第一步。

英文摘要:

We compute the ground-state properties of finite systems of neutrons in an external harmonic trap, interacting via the Minnesota potential, using the "exact-exchange" form of orbital-dependent density functional theory. We compare our results with Hartree-Fock calculations and find very close agreement. Within the context of the interaction studied, we conclude that this simple orbital-dependent functional brings conventional nuclear density functional theory to the level of Hartree-Fock in an ab initio fashion. Our work is a first step towards higher-order ab initio nuclear functionals based on realistic nucleon-nucleon interactions.
