摘要

我们研究了库仑晶体形式的二元离子混合物（BIMs）的静电能，重点是有序晶体。我们考虑了 15 种不同的二元 bcc 样晶格，精确计算了它们的静电能，并用统一方程对它们进行了近似。这些结果扩展了文献中已有的结果。我们与之前的部分结果进行了详细比较，特别是使用线性混合规则近似的计算结果。此外，还概述了无序 BIM 的情况。预计这些结果将有助于探索紧凑恒星、实验室等离子体和技术应用中的多组分库仑系统。

Electrostatic energy of solid binary ionic mixtures.

We study the electrostatic energy of binary ionic mixtures (BIMs) in the form of Coulomb crystals with the main focus on ordered crystals. We consider 15 different binary bcc-like lattices, accurately calculate their electrostatic energies, and approximate them by a unified equation. These results extend those available in the literature. A detailed comparison with selected previous results is made, particularly, using previous calculations in the linear mixing rule approximation. The case of disordered BIMs is also outlined. The results are expected to be useful for exploring multicomponent Coulomb systems in compact stars, laboratory plasmas, and technological applications.
