摘要
利用基于手性有效场理论的核相互作用自洽格林函数(SCGF)方法研究了均质核物质。所采用的方法结合了最先进的三阶代数图解构造近似和高尔科夫相关性,能够计算核物质的状态方程(EOS)和单粒子性质。用我们的方法和耦合簇理论计算出的 EOS 非常吻合。讨论了单核谱函数和动量分布,以深入了解相互作用核物质的动力学。
Ab initio Green's functions approach for homogeneous nuclear matter
Homogeneous nuclear matter is investigated using the \textit{ab initio}
Self-consistent Green's function (SCGF) approach with nuclear interactions
based on chiral effective field theory. The employed method, which combines the
state-of-the-art algebraic diagrammatic construction approximation at third
order with Gorkov correlations, is capable of computing both the equation of
state (EOS) and single-particle properties of nuclear matter. The EOS
calculated with our approach and coupled-cluster theory are shown to agree very
well. The one-nucleon spectral functions and the momentum distributions are
discussed to gain insights into the dynamics of the interacting nuclear matter.
