非一致自治一维排斥最近邻反应扩散模型

Nonuniform autonomous one-dimensional exclusion nearest-neighbor reaction-diffusion models

Amir Aghamohammadi, Mohammad Khorrami

摘要:

本文考虑了最一般的带边界的一维格点上的非均匀反应扩散模型,其相关函数的时间演化方程是封闭的。采用传递矩阵法求出静态解。可以看出,如果反应速率满足一定的条件,则该传递矩阵可以以封闭形式获得。我们称这种模式为超自主。可能的静态相变的这种模型进行了调查。最后,作为超自治模型的一个例子,介绍了一个非均匀选举模型,并给出了显式求解。

英文摘要:

The most general nonuniform reaction-diffusion models on a one-dimensional lattice with boundaries, for which the time evolution equations of corre- lation functions are closed, are considered. A transfer matrix method is used to find the static solution. It is seen that this transfer matrix can be obtained in a closed form, if the reaction rates satisfy certain conditions. We call such models superautonomous. Possible static phase transitions of such models are investigated. At the end, as an example of superau- tonomous models, a nonuniform voter model is introduced, and solved explicitly.
