耦合逻辑映象格子的相干性与斑图形成

Coherence and pattern formation in coupled logistic-map lattices

Maciej Janowicz, Arkadiusz Orłowski

摘要:

介绍了耦合映象格子时空行为的三种定量度量:约化密度矩阵、约化波函数和粒子数模拟。它们为相干性概念提供了定量的意义,相干性概念在复杂系统的背景下被相当直观地使用。它们的行为表明,逻辑耦合映象晶格接近类似玻色粒子系统的凝聚态的状态。此外,还研究了二维耦合映象格子中基于Logistic映射的斑图形成的非线性参数、扩散常数、初始条件和边界条件。

英文摘要:

Three quantitative measures of the spatiotemporal behavior of the coupled map lattices: reduced density matrix, reduced wave function, and an analog of particle number, have been introduced. They provide a quantitative meaning to the concept of coherence which in the context of complex systems have been used rather intuitively. Their behavior suggests that the logistic coupled-map lattices approach the states which resemble the condensed states of systems of Bose particles. In addition, pattern formation in two-dimensional coupled map lattices based on the logistic mapping has been investigated with respect to the non-linear parameter, the diffusion constant and initial as well as boundary conditions.
