一类左可渗透两种群非对称排斥过程的矩阵乘积解

Matrix product solution of a left-permeable two-species asymmetric exclusion process

Arvind Ayyer, Caley Finn, Dipankar Roy

摘要:

我们研究了两个物种的部分不对称排斥过程的左边界是可渗透的“慢”的物种,但右边界是不是。我们找到了一个矩阵乘积解的定态,和精确的定态相图的密度和电流。通过计算每个物种在边界处的密度,我们发现了固定相中的进一步结构。特别是,我们发现,较慢的物种可以达到并积累在远边界,即使在这些颗粒的体积密度接近零的阶段。

英文摘要:

We study a two-species partially asymmetric exclusion process where the left boundary is permeable for the `slower' species but the right boundary is not. We find a matrix product solution for the stationary state, and the exact stationary phase diagram for the densities and currents. By calculating the density of each species at the boundaries, we find further structure in the stationary phases. In particular, we find that the slower species can reach and accumulate at the far boundary, even in phases where the bulk density of these particles approaches zero.
