含第二类粒子的TASEP中某些转移概率的行列式表示

Determinant representation for some transition probabilities in the TASEP with second class particles

Sakuntala Chatterjee, Gunter M. Schütz

摘要:

研究了无限整数格点上完全非对称简单排斥过程(TASEP)的跃迁几率,其中第一类和第二类粒子的个数是有限的,但可以是任意的。利用Bethe近似,我们给出了这些量的Bethe波函数的显式表达式。在下一步中,它被严格证明,该表达式可以写在一个紧凑的行列式形式的情况下,第一和第二类粒子的顺序不随时间变化。一个独立的几何方法提供了深入了解这些结果,使我们能够推广到多类TASEP的行列式的解决方案。

英文摘要:

We study the transition probabilities for the totally asymmetric simple exclusion process (TASEP) on the infinite integer lattice with a finite, but arbitrary number of first and second class particles. Using the Bethe ansatz we present an explicit expression of these quantities in terms of the Bethe wave function. In a next step it is proved rigorously that this expression can be written in a compact determinantal form for the case where the order of the first and second class particles does not change in time. An independent geometrical approach provides insight into these results and enables us to generalize the determinantal solution to the multi-class TASEP.
