自洽格林函数理论在核中的应用

Recent Applications of Self-Consistent Green's Function Theory to Nuclei

Carlo Barbieri, Francesco Raimondi, Christopher McIlroy

摘要:

我们讨论了最近基于自洽格林函数理论的\emph{ab initio}计算。结果发现,一个简单的扩展的形式主义,以考虑两个核子散射的模型空间之外,允许计算非软相互作用。有了这个,就有可能对格点量子色动力学势进行预言,到目前为止,在$m_π= 0.47$ GeV/c $^2$的π介子质量下得到的。更传统的计算,使用饱和手征EFT力产生一个很好的描述核反应和核子敲除光谱。

英文摘要:

We discuss recent \emph{ab initio} calculations based on self-consistent Green's function theory. It is found that a simple extension of the formalism to account for two-nucleon scattering outside the model space allows to calculate non-soft interactions. With this, it is possible to make predictions for Lattice QCD potentials, obtained so far at pion masses of $m_π= 0.47$GeV/c$^2$. More traditional calculations that use saturating chiral EFT forces yield a good description of nuclear responses and nucleon knockout spectroscopy.
