周期TASEP的极限单点分布

Limiting one-point distribution of periodic TASEP

Jinho Baik, Zhipeng Liu, Guilherme L. F. Silva

摘要:

空间周期完全非对称简单排它过程的单点分布的弛豫时间极限是周期域中KPZ普适类模型的普适单点分布.与无限长线的情况不同,极限单点分布依赖于非平凡的缩放时间参数。我们研究了这种分布的情况下的周期性步骤和平坦的初始条件的几个属性。我们证明了该分布从小时限内的Tracy-Widom分布变化到大时限内的高斯分布,并且还获得了所有时间的右尾估计。此外,我们建立了一个连接到可积的微分方程,如KP方程,耦合系统的mKdV和非线性热方程,和KdV方程。

英文摘要:

The relaxation time limit of the one-point distribution of the spatially periodic totally asymmetric simple exclusion process is expected to be the universal one point distribution for the models in the KPZ universality class in a periodic domain. Unlike the infinite line case, the limiting one point distribution depends non-trivially on the scaled time parameter. We study several properties of this distribution for the case of the periodic step and flat initial conditions. We show that the distribution changes from a Tracy-Widom distribution in the small time limit to the Gaussian distribution in the large time limit, and also obtain right tail estimate for all time. Furthermore, we establish a connection to integrable differential equations such as the KP equation, coupled systems of mKdV and nonlinear heat equations, and the KdV equation.
