模型能量密度泛函的从头算推导
Ab Initio Derivation of Model Energy Density Functionals
摘要：
我提出了一个简单和易于管理的方法，允许推导耦合常数的模型能量密度泛函（EDF）直接从有限费米子系统的从头计算进行。一个证明的原则应用程序允许有限核，通过使用核非本地Gogny功能，准本地Skyrme功能的耦合常数确定的链接属性。该方法不依赖于无限费米子系统的性质，而是依赖于有限系统的从头计算。它还允许量化的优点，不同的模型EDF在描述从头计算的结果。
英文摘要：
I propose a simple and manageable method that allows for deriving coupling constants of model energy density functionals (EDFs) directly from ab initio calculations performed for finite fermion systems. A proof-of-principle application allows for linking properties of finite nuclei, determined by using the nuclear nonlocal Gogny functional, to the coupling constants of the quasilocal Skyrme functional. The method does not rely on properties of infinite fermion systems but on the ab initio calculations in finite systems. It also allows for quantifying merits of different model EDFs in describing the ab initio results.
