We use Langevin dynamics simulations to study the growth kinetics and the steady-state properties of condensed clusters in a dilute two-dimensional system of particles that are all different (APD) in the sense that each particle is characterized by a randomly chosen interaction parameter. The growth exponents, the transition temperatures, and the steady-state properties of the clusters and of the surrounding gas phase are obtained and compared with those of one-component systems. We investigate the fractionation phenomenon, i.e., how particles of different identities are distributed between the coexisting mother (gas) and daughter (clusters) phases. We study the local organization of particles inside clusters, according to their identity-neighbourhood identity ordering (NIO)-and compare the results with those of previous studies of NIO in dense APD systems.
我们使用朗之万动力学模拟来研究在一个稀有的二维粒子系统中凝聚团簇的生长动力学和稳态特性，在这个系统中，每个粒子的相互作用参数都是随机选择的，因此所有粒子都是不同的（APD）。我们得到了生长指数、转变温度以及团簇和周围气相的稳态特性，并将它们与单一组分系统进行了比较。我们研究了分馏现象，即不同身份的粒子如何在共存的母体（气体）和子体（团簇）相之间分配。我们根据粒子的身份-邻居身份排序（NIO）研究了粒子在团簇内部的局部组织，并将结果与之前对密集 APD 系统中 NIO 的研究结果进行了比较。
