非对称简单排斥过程的平衡网络

Balance network of asymmetric simple exclusion process

Takahiro Ezaki, Katsuhiro Nishinari

摘要:

研究了非对称简单排它过程(ASEP)的平衡网络。由ASEP组成的子系统之间通过双向链路相互连接,从而导致每对子系统之间的平衡。该网络包括一些具体的重要情况下,讨论了早期的工作,如ASEP与朗缪尔动力学,多车道和有限的水库。根据粒子的平衡性质,精确地给出了定态粒子的概率分布的因式分解形式。虽然该系统有非平衡部分,但表达式在基于平衡态的统计力学框架内得到了很好的描述。此外,整体的论点并不依赖于网络结构,在这项工作中获得的知识适用于广泛的问题。

英文摘要:

We investigate a balance network of the asymmetric simple exclusion process (ASEP). Subsystems consisting of ASEPs are connected by bidirectional links with each other, which results in balance between every pair of subsystems. The network includes some specific important cases discussed in earlier works such as the ASEP with the Langmuir kinetics, multiple lanes and finite reservoirs. Probability distributions of particles in the steady state are exactly given in factorized forms according to their balance properties. Although the system has nonequilibrium parts, the expressions are well described in a framework of statistical mechanics based on equilibrium states. Moreover, the overall argument does not depend on the network structures, and the knowledge obtained in this work is applicable to a broad range of problems.
