论文摘要
在本文中，我们研究了在开放的一维晶格上定义的单物种不对称简单排除过程的多种概括。我们设计了一个确切的投影方案，以根据所有物种的密度和电流来找到相图。在大多数阶段中，由于动态驱动，系统中没有一个或多个物种。我们在相图的某些区域也观察到冲击。我们使用数值模拟证实的广义冲击结构来解释密度曲线。
In this article, we investigate a multispecies generalization of the single-species asymmetric simple exclusion process defined on an open one-dimensional lattice. We devise an exact projection scheme to find the phase diagram in terms of densities and currents of all species. In most of the phases, one or more species are absent in the system due to dynamical expulsion. We observe shocks as well in some regions of the phase diagram. We explain the density profiles using a generalized shock structure that is substantiated by numerical simulations.
