我们提出了一种理论方法,从X射线汤姆逊散射数据导出的直流电导率的温暖的致密物质(WDM)。在较宽的温度范围内(0.08 eV < k B T < 80 eV)给出了凝聚态密度下铝的电导率的预测。强相关效应考虑到离子结构因素。屏蔽和泡利阻塞通过赝势描述。与其他的理论模型和模拟,以及与实验测量的液态金属制度和最近的实验在WDM制度的结果进行了比较。
We present a theoretical approach to derive the dc conductivity of warm dense matter (WDM) from x-ray Thomson scattering data. Predictions for the conductivity of aluminum at condensed matter densities are given within a wide temperature range ( 0.08 eV < k B T < 80 eV). Strong correlation effects are taken into account by ionic structure factors. Screening and Pauli blocking are described via a pseudopotential. The results are compared with other theoretical models and simulations as well as with experimental measurements in the liquid metal regime and recent experiments in the WDM regime.
