摘要
主要介绍了复杂网络中的热传导行为。回顾和综合评述了近些年来微观低维系统热传导特性的工作进展,介绍了低维系统中的反常热传导现象,包括热导率随系统的尺寸、温度等的影响,界面热阻,负微分热阻,整流效应等项目。因复杂网络中的热传导特性的研究目前还处于初步阶段,所以就链间耦合网络、随机网络、无标度网络以及高集聚性网络展开详细讨论。界面热阻,热流的局域化的存在,网络结点度的异质性和网络的集聚系数对网络的热传导特性的影响,以及热整流效应等也都逐一阐释。最后,总结了在复杂网络上的热传导特性研究工作的同时,也提出了今后在这个领域可以深入讨论的三大类问题。
This paper reviews the characteristic behavior of heat transport on complex networks in general.We summarize the frontier of the research in abnormal transport in low dimensional systems,including the size and temperature dependence of heat conductivity,interfacial resistance,rectification,etc.Since the research of heat transport on complex networks just started within a few years,we emphasize on discussing the characteristics of the heat conduction of coupled chain,random,scale-free and highly clustered networks in detail.It is found that the interfacial resistance,flux localization,heterogeneity of network nodes and the clustering have inter-related effects on the characteristics of the heat transport of complex networks.The last but not least are the proposed three major categories of potential topics that can be done in the future.
