论文摘要
最近，从头算技术已成功连接到传统的价空间模型。这样一来，他们可以明确地提供从头开始的壳牌模型有效的哈密顿量，也可以限制经验的构建。在目前的工作中，分析了遵循核能密度功能（EDF）方法的类似途径的可能性。为了实现这一联系，两种理论技术具有工具性：最近提出的AB INIO pGCM-PT多体形式主义和MR-IMSRG对核哈密顿官的预处理。基于正式的论点和数值结果，简要讨论了可能的新研究线，即以低计算成本计算有效的汉密尔顿人，以限制经验性的汉密尔顿人，或通过有效的现场理论直接生产这些研究，而这些理论仍有待发明。
Recently, ab initio techniques have been successfully connected to the traditional valence-space shell model. In doing so, they can either explicitly provide ab initio shell-model effective Hamiltonians or constrain the construction of empirical ones. In the present work, the possibility to follow a similar path for the nuclear energy density functional (EDF) method is analyzed. For this connection to be actualized, two theoretical techniques are instrumental: the recently proposed ab initio PGCM-PT many-body formalism and the MR-IMSRG pre-processing of the nuclear Hamiltonian. Based on both formal arguments and numerical results, possible new lines of research are briefly discussed, namely to compute ab initio EDF effective Hamiltonians at low computational cost, to constrain empirical ones or to produce them directly via an effective field theory that remains to be invented.
