文章回顾了利用相对论Hartree-Fock理论研究核物质对称能的一些相关工作.首先简要介绍了新发展的密度依赖的相对论Hartree-Fock理论描述核物质体系的理论框架.随后从三个方面总结了相对论Hartree-Fock理论中的对称能物理,包括交换项对增强对称能的密度依赖性所起的作用,超子引起的交换项效应对于对称能的额外软化作用,以及提取对称能中的自洽张量力效应等.最后,讨论了通过约束对称能的密度依赖行为改进理论模型的一点建议.
This paper reviews some related work on relativistic Hartree-Fock theory to study the symmetry energy of nuclear materials.Firstly, the theoretical framework of the newly developed density-dependent relativistic Hartree-Fock theory to describe the nuclear matter system is briefly introduced.After that, the theory of relativity Symmetry-energy physics in the Hartree-Fock theory includes the role of exchange terms in increasing the density-dependent dependence of symmetry energy, the extra softening effect of exchange-term effects on the symmetry energy due to hyperons, and the self-consistent expansion of symmetry energy Quantum effect, etc.Finally, we discuss some suggestions to improve the theoretical model by constraining the density-dependent behavior of symmetry energy.
