论文摘要
使用具有自洽等离子体物理学的模型的热量等离子体的光学性能计算是对高能量密度科学的巨大挑战。在这里，我们利用了一个最近开发的电子结构模型，该模型使用多个散射理论来求解致密等离子体的Kohn-Sham密度功能理论方程。我们计算这种制度中的不透明性，验证该方法，并将其应用于CR，NI和FE的不透明度的最新实验测量。对于CR和NI的准室内区域中，可以找到良好的一致性，而该方法的自洽等离子体物理不能解释模型与FE的实验之间观察到的差异。
The calculation of the optical properties of hot dense plasmas with a model that has self-consistent plasma physics is a grand challenge for high energy density science. Here we exploit a recently developed electronic structure model that uses multiple scattering theory to solve the Kohn-Sham density functional theory equations for dense plasmas. We calculate opacities in this regime, validate the method, and apply it to recent experimental measurements of opacity for Cr, Ni, and Fe. Good agreement is found in the quasicontinuum region for Cr and Ni, while the self-consistent plasma physics of the approach cannot explain the observed difference between models and the experiment for Fe.
