Different advanced bridge function closures are utilized to investigate the structural and thermodynamic properties of dense Yukawa one‐component plasma liquids within the framework of integral equation theory. The isomorph‐based empirically modified hypernetted‐chain, the variational modified hypernetted‐chain, the Rogers–Young, and the Ballone–Pastore–Galli–Gazzillo approaches are compared at the level of thermodynamic properties, radial distribution functions, and bridge functions. The comparison, based on accuracy and computational speed, concludes that the two modified hypernetted‐chain approaches are superior and singles out the isomorph‐based variant as the most promising alternative to computer simulations of structural properties of dense Yukawa liquids. The possibility of further improvement through artificial crossover to exact asymptotic limits is studied.

关于稠汤汤液单组分等离子体液体的高级积分方程理论描述

在积分方程理论的框架内，使用了不同的高级桥函数闭塞来研究稠密的汤河一组分等离子体液体的结构和热力学性质。在热力学性质，径向分布函数和桥函数的水平上，比较了基于同构异构体的经验修饰的超网状链，变体修饰的超网状链，Rogers–Young和Ballone–Pastore–Galli–Gazzillo方法。根据准确性和计算速度进行的比较得出的结论是，两种改进的超网状链方法均具有优越性，并指出基于同晶型的变体是稠密汤河液体的计算机模拟结构特性的最有希望的替代方法。
