我们研究具有随机能量扩散的热传导模型。我们获得了描述所有相关函数演化的双粒子过程。能量协方差的精确表达式在存在电流的情况下表现出长程相关性。我们讨论该模型与简单对称排除过程的形式联系。
We study a model of heat conduction with stochastic diffusion of energy. We obtain a dual particle process which describes the evolution of all the correlation functions. An exact expression for the covariance of the energy exhibits long-range correlations in the presence of a current. We discuss the formal connection of this model with the simple symmetric exclusion process.
