我们证明了在一个大的有限系统中一维畴壁的布朗运动产生一个ω(-3/2)功率谱。这被成功地应用于具有开边界的完全不对称简单排斥过程。我们的理论和数值计算结果之间的一个很好的协议是在畴壁运动占主导地位的频率范围内,系统的离散性是无效的。
We show that Brownian motion of a one-dimensional domain wall in a large but finite system yields a omega(-3/2) power spectrum. This is successfully applied to the totally asymmetric simple exclusion process with open boundaries. An excellent agreement between our theory and numerical results is obtained in a frequency range where the domain wall motion dominates and the discreteness of the system is not effective.
