KPZ普适类中的可积涨落

Integrable fluctuations in the KPZ universality class

Daniel Remenik

摘要:

KPZ不动点是一个标度不变的马尔可夫过程,它是一维随机界面生长模型的普遍标度极限,即一维KPZ普适类。在这次调查中,我们回顾了建设的KPZ不动点和一些历史,导致它,特别是通过完全不对称的简单排它过程,一个特殊的可解模型类的精确解。我们还解释了如何建设揭示了KPZ不动点作为一个随机可积系统,以及如何从这一点,它的有限维分布满足经典的可积色散偏微分方程,Kadomtsev-Petviashvili(KP)方程。

英文摘要:

The KPZ fixed point is a scaling invariant Markov process which arises as the universal scaling limit of a broad class of models of random interface growth in one dimension, the one-dimensional KPZ universality class. In this survey we review the construction of the KPZ fixed point and some of the history that led to it, in particular through the exact solution of the totally asymmetric simple exclusion process, a special solvable model in the class. We also explain how the construction reveals the KPZ fixed point as a stochastic integrable system, and how from this it follows that its finite dimensional distributions satisfy a classical integrable dispersive PDE, the Kadomtsev-Petviashvili (KP) equation.
