非齐次离散排他过程

Inhomogeneous discrete-time exclusion processes

N. Crampe, K. Mallick, E. Ragoucy, M. Vanicat

摘要:

本文研究了具有周期或开边界条件的离散时间马氏过程,并研究了其在整体上的非齐次速率。马尔可夫矩阵由前面介绍的非齐次转移矩阵给出,证明了量子自旋链的可积性。我们表明,这些过程有一个简单的图形解释,并对应于一个连续的更新。我们使用矩阵变换计算它们的定态,并将它们的归一化因子表示为舒尔多项式。Bethe根和李-杨零点之间的联系也被指出。

英文摘要:

We study discrete time Markov processes with periodic or open boundary conditions and with inhomogeneous rates in the bulk. The Markov matrices are given by the inhomogeneous transfer matrices introduced previously to prove the integrability of quantum spin chains. We show that these processes have a simple graphical interpretation and correspond to a sequential update. We compute their stationary state using a matrix ansatz and express their normalization factors as Schur polynomials. A connection between Bethe roots and Lee-Yang zeros is also pointed out.
