摘 要:相对论Brueckner-Hartree-Fock(RBHF)理论是相对论框架下重要的第一性原理方法,仅包含两体力即可以满意描述核物质的饱和性质。在完备的Dirac空间中自洽求解核物质RBHF方程,唯一确定了单粒子势的标量和矢量分量,避免了已有工作中由于忽略负能态所导致的不确定性,解决了40多年来RBHF计算中不能唯一确定单粒子势的问题。本工作简要回顾RBHF理论的发展历史,阐述包含负能态做RBHF计算的必要性,介绍利用完备Dirac空间的RBHF理论,研究核物质性质和中子星物质性质的最新进展,包括有效质量、纯中子物质的每核子结合能、对称核物质和纯中子物质的压强、中子星物质的粒子分数和状态方程、中子星的质量-半径关系和潮汐形变等。最后展望了完备Dirac空间的RBHF理论在确定密度泛函理论参数、微观描述核子-原子核弹性散射和研究中子星内部强子-夸克相变等方面的可能应用。Relativistic Brueckner-Hartree-Fock(RBHF)theory is one of the most important ab initio methods in the relativistic framework,where the saturation properties of nuclear matter could be described satisfactorily with only considering twobody forces.By achieving the self-consistent solution of the RBHF equations for nuclear matter in the full Dirac space,the scalar and vector components of the single-particle potential have been determined uniquely,the uncertainties caused by the neglect of negative-energy states(NESs)have been avoided,and the long-standing problem over 40 years of not being able to uniquely determine the single-particle potential has been solved.The history of the RBHF theory is briefly reviewed,and the necessity of considering NESs is illustrated.The latest results of nuclear matter and neutron star matter by the RBHF theory in the full Dirac space are discussed,including the effective mass,the binding energy per particle of pure neutron matter,the pressure of symmetric nuclear matter and pure neutron matter,the particle fractions as well as the equation of state for neutron star matter,and the mass-radius relation as well as the tidal deformability of a neutron star.Possible applications of the RBHF theory in the full Dirac space are also discussed,including the calibration of the parameters in density functional theory,the microscopic description of nucleon-nucleus elastic scattering,and the research on the hadron-quark transition inside neutron stars.
