用密度泛函理论的有效单粒子描述方法处理了热稠密等离子体中的多体问题。出现了三个关键思想,即,(i)中性假原子(NPA)概念描述了原子核及其在等离子体中的电子分布,(ii)跳跃电子的概念描述了离子分布对电子的影响,这些电子被证明是以束缚电子、跳跃电子和自由电子的形式存在的,以及(iii)迁移率边缘的概念取代了当我们进入更密集的等离子体时的连续边缘的概念
The many-body problem in a hot dense plasma is treated using the effective one-particle description of density-functional theory. Three key ideas emerge, viz., (i) the neutral-pseudoatom (NPA) concept to describe a nucleus plus its electron distribution in the plasma, (ii) the concept of hopping electrons describing the effect of the ion-distribution on the electrons, which are shown to exist as bound, hopping, and free electrons, and (iii) the concept of the mobility edge replacing that of the continuum edge as we go to denser plasmas
