摘要:

具有广义更新的完全不对称简单排他过程是离散时间完全不对称排他过程的一个版本,包含控制粒子聚集程度的额外粒子间相互作用。尽管该模型在环和无限格子上被证明可积,但在开放链上主要进行了数值研究,甚至连其相图都没有解析结果。本文引入与模型无限平移不变稳态相关的新边界条件,从而解析地获得精确相图。我们详细讨论了相图,并通过广泛的数值模拟证实了解析预测。

英文摘要:

The totally asymmetric simple exclusion process with generalized update is a version of the discrete time totally asymmetric exclusion process with an additional inter-particle interaction that controls the degree of particle clustering. Though the model was shown to be integrable on the ring and on the infinite lattice, on the open chain it was studied mainly numerically, while no analytic results existed even for its phase diagram. In this paper we introduce new boundary conditions associated with the infinite translation invariant stationary states of the model, which allow us to obtain the exact phase diagram analytically. We discuss the phase diagram in detail and confirm the analytic predictions by extensive numerical simulations.
