Application of Statistical Self-consistent Field INFERNO Model to Equation of State and Hugoniot of Gold

  • 摘要: 以Liberman的统计自洽场INFERNO模型为基础,通过自洽求解每个温度密度点的统计自洽场Dirac方程,获得了金在宽广的温度与密度范围内的物态方程,其中包括以维里定理为基础的冷能、冷压计算,以及在宽广的温度与密度范围内的电子热能、热压计算。对离子热运动部分,采用简单的自由体积模型给出其热能及热压。在物态方程的基础上,又计算了金的理论雨贡纽,得到了与实验符合得比较好的结果。研究结果表明,INFERNO模型可用于物质在宽广的温度与密度范围内的物态方程计算。
