摘要

利用明亮的超短 X 射线脉冲瞬时产生并描述暖致密铜。随着脉冲强度的增加，铜的不透明度发生了强烈变化。所记录的 X 射线吸收光谱得到了理论电子结构模型的证实，使人们得以深入了解暖致密物质形成过程中的非平衡电子动力学。

Nonlinear absorption of an X-ray pulse during the formation of warm dense matter

A bright, ultrashort X-ray pulse is used to transiently create and characterize warm dense copper. As the pulse intensity is increased, the opacity of copper is strongly altered. The recorded X-ray absorption spectra, substantiated by a theoretical electronic structure model, provide insight into the non-equilibrium electron dynamics during the formation of warm dense matter.
