耦合非平衡系统中有序相的动力学性质

Ordered phases in coupled nonequilibrium systems: dynamic properties

Shauri Chakraborty, Sakuntala Chatterjee, Mustansir Barma

摘要:

本文研究了两类粒子平流耦合非平衡系统中有序相的动力学性质。景观的局部动态也受到粒子的影响。在一个配套文件中,我们提出了静态性能的不同阶段出现的双向耦合参数是不同的。在本文中,我们讨论的动力学。我们发现,在有序相宏观粒子团簇移动遍历的时间尺度上的系统大小呈指数增长,但有序景观显示动态在更快的时间尺度增长的系统大小的权力。我们提出了一个尺度分析,描述了几个动态的关联函数的景观在稳态测量。

英文摘要:

We study the dynamical properties of the ordered phases obtained in a coupled nonequilibrium system describing advection of two species of particles by a stochastically evolving landscape. The local dynamics of the landscape also gets affected by the particles. In a companion paper we have presented static properties of different phases that arise as the two-way coupling parameters are varied. In this paper we discuss the dynamics. We show that in the ordered phases macroscopic particle clusters move over an ergodic time-scale growing exponentially with system size but the ordered landscape shows dynamics over a faster time-scale growing as a power of system size. We present a scaling ansatz that describes several dynamical correlation functions of the landscape measured in steady state.
