在本文中,我们提出了一种通用的方法来计算期望值的零程过程(ZRP),使用的精确形式的分区函数。作为一个例子,我们提供的基本图(通量密度图)的不对称排斥过程对应的ZRP。我们表示的配分函数的稳定状态的Lauricella超几何函数,从而有两个确切的基本图,每个并行和随机顺序更新规则。同时,从平衡统计力学的角度出发,我们在正则系综中进行了工作,但所得结果与前人在巨正则系综中所做的工作确实一致。
In this paper, we propose a general way of computing expectation values in the zero-range process (ZRP), using an exact form of the partition function. As an example, we provide the fundamental diagram (the flux–density plot) of the asymmetric exclusion process corresponding to the ZRP. We express the partition function for the steady state by the Lauricella hypergeometric function, and thereby have two exact fundamental diagrams each for the parallel and random sequential update rules. Meanwhile, from the viewpoint of equilibrium statistical mechanics, we work within the canonical ensemble but the result obtained is certainly in agreement with previous works done in the grand-canonical ensemble.
