低能QCD约束下的能量密度泛函

Nuclear Energy Density Functionals Constrained by Low-Energy QCD

Dario Vretenar

摘要:

评述了能量密度泛函的微观框架,它建立了低能QCD与原子核结构的直接联系,综合了有效场论方法和密度泛函理论的基本原理。利用低能极限下QCD的两个密切相关的特征:真空凝聚体的介质内变化和手征对称性的自发破缺,发展了一个相对论性能量密度泛函,并将其应用于球形核和形变核基态性质的研究.

英文摘要:

A microscopic framework of nuclear energy density functionals is reviewed, which establishes a direct relation between low-energy QCD and nuclear structure, synthesizing effective field theory methods and principles of density functional theory. Guided by two closely related features of QCD in the low-energy limit: a) in-medium changes of vacuum condensates, and b) spontaneous breaking of chiral symmetry; a relativistic energy density functional is developed and applied in studies of ground-state properties of spherical and deformed nuclei.
