在经典成核理论的背景下，我们研究了单组分等离子体（OCP）的结晶速率。从我们的推导的自由能的任意分布的固体团簇嵌入在液相中，我们得到的OCP的稳态成核率作为库仑耦合参数F的函数。我们的结果的速率是根据最近的分子动力学模拟，但它是由许多数量级比以前的分析估计。进一步的分子动力学模拟的成核率的过冷液体OCP的几个值的F将澄清这个过程的物理。
We investigate the crystallization rate of a one-component plasma (OCP) in the context of classical nucleation theory. From our derivation of the free energy of an arbitrary distribution of solid clusters embedded in a liquid phase, we derive the steady-state nucleation rate of an OCP as a function of the Coulomb coupling parameter F. Our result for the rate is in accordance with recent molecular dynamics simulations, but it is greater than that of previous analytical estimates by many orders of magnitude. Further molecular dynamics simulations of the nucleation rate of a supercooled liquid OCP for several values of F would clarify the physics of this process.
