我们提出了具有 bcc、fcc 和液相的电荷稳定胶体相图的密度泛函理论。该理论要求包含涉及液体三体直接相关函数的项，但即使这些项的简单参数化也能再现实验相图的特征。我们根据我们的理论做出了额外的可直接测试的预测。
We present a density-functional theory for the phase diagram of charge-stabilized colloids with bcc, fcc, and liquid phases. The theory requires inclusion of terms involving the three-body direct correlation function of the liquid, but even a simple parametrization of these terms reproduces the features of the experimental phase diagram. We make additional directly testable predictions from our theory.
