位形空间中Faddeev-Yakubovsky方程描述四核子和五核子系统

Description of Four- and Five-Nucleon Systems by Solving Faddeev-Yakubovsky Equations in Configuration Space

Rimantas Lazauskas, Jaume Carbonell

摘要:

Faddeev Yakubovsky方程在非相对论动力学框架下构成了量子力学N体问题的严格公式。它们允许薛定谔方程的束缚态和散射态的精确解。在这篇综述中,我们将提出一般的形式主义,以及我们用来解决Faddeev Yakubovsky方程在配置空间的数值工具。我们将详细考虑基于现代现实核哈密顿量的四核子和五核子系统的描述。将总结这一领域的最新成就。一些仍然有争议的问题与核哈密顿以及传统的数值方法来解决一些核子问题将突出。

英文摘要:

The Faddeev Yakubovsky equations constitute a rigorous formulation of the quantum mechanical N body problem in the framework of non relativistic dynamics. They allow the exact solutions of the Schrodinger equation for bound and scattering states to be obtained. In this review, we will present the general formalism as well as the numerical tools we use to solve Faddeev Yakubovsky equations in configuration space. We will consider in detail the description of the four and five nucleon systems based on modern realistic nuclear Hamiltonians. Recent achievements in this domain will be summarized. Some of the still controversial issues related with the nuclear Hamiltonians as well as the numerical methods traditionally employed to solve few nucleon problems will be highlighted.
