摘要

以汤川系统为例，分析了具有软相互作用势的系统的结晶。详细研究了旋转不变式 q4 和 q6 平面上的结晶路径。最近提出的使用 12 个近邻计算的不变式 bcc1 和 bcc2 被首次用于研究结晶。研究表明，将旋转不变性技术和 Voronoi 多面体方法结合起来，我们可以非常简单地识别系统凝固过程中形成的所有类型的类固态簇，包括传统方法难以识别的 bcc 类簇。

On the Identification of Solid-Like Clusters in a Crystallizing Yukawa System

The crystallization of systems with soft interaction potentials is analyzed for a Yukawa system as an example. The crystallization pathway in the plane of rotational invariants q₄ and q₆ is studied in detail. The recently proposed invariants bcc₁ and bcc₂, calculated using 12 nearest neighbors, are applied for the first time to study the crystallization. It is shown that the combination of the rotational invariant technique and the method of Voronoi polyhedra allows us to identify quite simply all types of solid-like clusters formed during the solidification of the system, including bcc-like clusters, which are hardly identified by conventional methods.
