含运动缺陷环上的对称排斥过程

Symmetric exclusion processes on a ring with moving defects

Rakesh Chatterjee, Sakuntala Chatterjee, Punyabrata Pradhan

摘要:

我们研究了存在均匀移动的多个缺陷或障碍的环上的对称简单排斥过程(SSEP)-早期提出的模型的推广[Phys. Rev. E 89,022138(2014)]。缺陷以均匀的速度移动,并局部改变粒子的跳跃率。我们探讨了缺陷对系统空间结构和输运性质的集体效应。我们还介绍了一个SSEP有序顺序(sitewise)更新,并阐明与我们的模型的密切联系。

英文摘要:

We study symmetric simple exclusion processes (SSEP) on a ring in the presence of uniformly moving multiple defects or disorders - a generalization of the model proposed earlier [Phys. Rev. E 89, 022138 (2014)]. The defects move with uniform velocity and change the particle hopping rates locally. We explore the collective effects of the defects on the spatial structure and transport properties of the system. We also introduce an SSEP with ordered sequential (sitewise) update and elucidate the close connection with our model.
