动力学反应中的场论方法:随机源和随机汇的作用

Field Theory Approach In Kinetic Reaction: Role Of Random Sources And Sinks

M. Hnatich, J. Honkonen, T. Lučivjanský

摘要:

在Doi型主方程二次量子化的场论模型框架下,研究了主方程描述中随机源和汇对反应动力学的影响.我们发现,随机源和汇显着影响模型的渐近行为,并确定两个普适性类时,用尺度分析来描述它们。我们比较的结果与Langevin方程描述相同的过程。

英文摘要:

In the framework of a field theoretic model obtained by second quantization of Doi-type master equation, we investigate the effects of random sources and sinks on the reaction kinetics in the master-equation description. We show that random sources and sinks significantly affect the asymptotic behavior of the model and identify two universality classes when describing them using scaling analysis. We compare the results with the Langevin-equation description of the same process.
