随机自复制聚集体中分形的出现

Emergence of fractal in aggregation with stochastic self-replication

M. K. Hassan, M. Z. Hassan, N. Islam

摘要:

我们提出并研究了一个简单的模型,它描述了随机自复制的布朗粒子的聚集动力学。一个精确的解决方案和标度理论一起提出的数值模拟,完全支持所有的理论研究结果。特别是,我们分析表明,颗粒尺寸分布函数具有动态缩放,我们验证了它的数值使用的数据崩溃的想法。此外,还找到了系统成为分形的条件,给出了系统的分维,并指出了分维与守恒量之间的关系。

英文摘要:

We propose and investigate a simple model which describes the kinetics of aggregation of Brownian particles with stochastic self-replication. An exact solution and the scaling theory are presented alongside numerical simulation which fully support all theoretical findings. In particular, we show analytically that the particle size distribution function exhibits dynamic scaling and we verified it numerically using the idea of data-collapse. Besides, the conditions under which the resulting system emerges as a fractal are found, the fractal dimension of the system is given and the relationship between this fractal dimension and a conserved quantity is pointed out.
