Time-dependent density functional theory applied to average atom opacity

We focus on studying the opacity of iron, chromium, and nickel plasmas at conditions relevant to experiments carried out Sandia National Laboratories [J. E. Bailey et al., Nature 517, 56 (2015)]. calculate photo-absorption cross-sections subsequent for using linear response time-dependent density functional theory (TD-DFT). Our results indicate that physics channel mixing accounted in TD-DFT leads an increase bound-free quasi-continuum, where models under-predict iron opacity. However, seen our calculations is only range 5-10%. Further, we do not see any change this trend chromium nickel. This behavior indicates effects explain trends observed experiments.
