论文摘要
我们介绍了一种新方法的第一个应用，该方法在[物理学杂志G：核与粒子物理学杂志，43，04LT01（2016）]中提出，以从Skyrme能量密度功能（EDF）的偶联常数从HABILIO HAMILTONIAN。通过使用定义Skyrme EDF的几个功能发电机，通过扰动Ab Initio，我们创建了一组元数据，然后将其用于约束功能的耦合常数。我们使用统计分析来获得这样的初始等效性Skyrme EDF。我们发现所得的功能描述了原子核的特性和无限的核物质。这可能指出，有必要从更复杂的发电机中构建从头算的等效功能。但是，我们还指出，从头算计算的当前精度可能不足以获取有意义的核EDF。
We present the first application of a new approach, proposed in [Journal of Physics G: Nuclear and Particle Physics, 43, 04LT01 (2016)] to derive coupling constants of the Skyrme energy density functional (EDF) from ab initio Hamiltonian. By perturbing the ab initio Hamiltonian with several functional generators defining the Skyrme EDF, we create a set of metadata that is then used to constrain the coupling constants of the functional. We use statistical analysis to obtain such an ab initio-equivalent Skyrme EDF. We find that the resulting functional describes properties of atomic nuclei and infinite nuclear matter quite poorly. This may point out to the necessity of building up the ab initio-equivalent functionals from more sophisticated generators. However, we also indicate that the current precision of the ab initio calculations may be insufficient for deriving meaningful nuclear EDFs.
