论文摘要
密集的等离子体发生在恒星，巨型行星和惯性融合实验中。这些等离子体的电子结构的准确建模可以预测材料特性，这些特性又可以用于模拟这些天体物理对象和陆地实验。但是对它们进行建模仍然是一个挑战。在这里，我们为此目的探索了Korringa-Kohn-Rostoker Green的功能（KKR-GF）方法。我们发现，它能够与其他最先进和可行的最新方法预测状态方程式。此外，与其他方法相比，计算成本与温度不会显着变化。此外，该方法不使用伪电势 - 始终如一地计算出核心状态。我们得出的结论是，KKR-GF是致密血浆模拟的非常有前途的方法。
Dense plasmas occur in stars, giant planets and in inertial fusion experiments. Accurate modeling of the electronic structure of these plasmas allows for prediction of material properties that can in turn be used to simulate these astrophysical objects and terrestrial experiments. But modeling them remains a challenge. Here we explore the Korringa-Kohn-Rostoker Green's function (KKR-GF) method for this purpose. We find that it is able to predict equation of state in good agreement with other state of the art methods, where they are accurate and viable. In addition, it is shown that the computational cost does not significantly change with temperature, in contrast with other approaches. Moreover, the method does not use pseudopotentials - core states are calculated self consistently. We conclude that KKR-GF is a very promising method for dense plasma simulation.
