N个相关二元变量的随机动力学与非广延统计力学

Stochastic dynamics of N correlated binary variables and non-extensive statistical mechanics

A. Kononovicius, J. Ruseckas

摘要:

非广延统计力学已被应用于描述各种具有内在关联和反馈回路的复杂系统。在这里,我们提出了一个动力学模型的基础上,先前提出的静态模型表现出在热力学极限的Tsallis熵与q<1的扩展性,以及一个q-高斯分布。动力学模型由一个一维的粒子环组成,其特征在于相关的二进制随机变量,允许根据一个简单的随机行走规则翻转。提出的动力学模型提供了一个洞察力的介观动力学特征的非广泛的统计力学可以出现从微观描述的系统。

英文摘要:

The non-extensive statistical mechanics has been applied to describe a variety of complex systems with inherent correlations and feedback loops. Here we present a dynamical model based on previously proposed static model exhibiting in the thermodynamic limit the extensivity of the Tsallis entropy with q<1 as well as a q-Gaussian distribution. The dynamical model consists of a one-dimensional ring of particles characterized by correlated binary random variables, which are allowed to flip according to a simple random walk rule. The proposed dynamical model provides an insight how a mesoscopic dynamics characterized by the non-extensive statistical mechanics could emerge from a microscopic description of the system.
