本文介绍了用Skyrme泛函描述低能核动力学的密度泛函方法的基本概念和最新进展。利用时间相关的密度泛函理论（TDDFT）对具有外部扰动的精确线性响应进行了研究。为了描述超越摄动状态的集体动力学，我们提出了一个解耦的集体子流形理论来描述基于TDDFT的慢运动。选定的应用程序展示了它们的性能质量和可行性。还讨论了数值方面的优点和缺点。
We present the basic concepts and our recent developments in the density functional approaches with the Skyrme functionals for describing nuclear dynamics at low energy. The time-dependent density-functional theory (TDDFT) is utilized for the exact linear response with an external perturbation. For description of collective dynamics beyond the perturbative regime, we present a theory of a decoupled collective submanifold to describe for a slow motion based on the TDDFT. Selected applications are shown to demonstrate the quality of their performance and feasibility. Advantages and disadvantages in the numerical aspects are also discussed.
