论文摘要
使用两种积分方程理论，超链链（HNC）-Ornstein-ornstein--沸点（OZ）和离子percus-yevick-yevick 2（ipy2）-oz来计算浸入电解质溶液中的类似电荷颗粒之间的有效相互作用。当采用HNC-oz理论时，有效相互作用的电解质浓度依赖性显示出重进入行为。相比之下，ipy2-oz理论并未表明行为。对其中一个模型系统进行了蒙特卡洛模拟，结果与使用HNC-OZ理论计算的结果一致。
Effective interactions between like-charged particles immersed in an electrolyte solution were calculated using two integral equation theories, hypernetted-chain (HNC)-Ornstein--Zernike (OZ) and ionic Percus--Yevick 2 (IPY2)-OZ. When the HNC-OZ theory was adopted, the electrolyte concentration dependence of the effective interaction showed a reentrant behavior. By contrast, the IPY2-OZ theory did not indicate the behavior. Monte Carlo simulations were performed for one of the model systems, and the results agreed qualitatively with those calculated using the HNC-OZ theory.
