对用于分析最近暖密物质（WDM）实验的成对相互作用和筛选模型的批判性评估
A critical assessment of models of pair-interactions and screening used in analyzing recent warm-dense matter (WDM) experiments
摘要：
超快激光实验产生了越来越可靠的温密物质（WDM）数据，但依赖于根深蒂固的简单理论模型。我们重新分析了两个专题实验，避免（i）{ \it ad hoc}核心排斥模型，（ii）“汤川屏蔽”模型和（iii）电子-离子平衡假设。一个精确的，快速的密度泛函中性赝原子模型耦合到一个超网链（HNC）方程与桥项被用来计算结构因子，X射线散射，压缩性，声子和电阻率。电子结构代码用于确认计算。汤川和核心排斥模型被证明是误导。
英文摘要：
Ultra-fast laser experiments yield increasingly reliable data on warm-dense matter (WDM), but rely on entrenched simplistic theoretical models. We re-analyze two topical experiments, avoiding (i) {\it ad hoc} core-repulsion models, (ii) "Yukawa screening" models and (iii) electron-ion equilibrium assumptions. An accurate, rapid density-functional neutral-pseudoatom model coupled to a hyper-netted-chain (HNC) equation with a bridge term is used to compute structure factors, X-Ray scattering, compressibility, phonons and resistivity. Electronic-structure codes are used to confirm the calculations. The Yukawa and core-repulsion models are shown to be misleading.
