利用Negele和Vautherin的密度矩阵展开(DME),向基于低动量相互作用的通用核能量密度泛函迈出了第一步。DME适用于非局域动量空间势,并推广到包括局域三体相互作用。比较了三体二甲醚的不同处方。给出了在Hartree-Fock水平上的探索性结果,以及在Kohn-Sham密度泛函理论的有效行动框架内进行系统改进的路线图。
A first step toward a universal nuclear energy density functional based on low-momentum interactions is taken using the density matrix expansion (DME) of Negele and Vautherin. The DME is adapted for non-local momentum space potentials and generalized to include local three-body interactions. Different prescriptions for the three-body DME are compared. Exploratory results are given at the Hartree-Fock level, along with a roadmap for systematic improvements within an effective action framework for the Kohn-Sham density functional theory.
