We study exact stationary properties of the one-dimensional Kardar-Parisi-Zhang (KPZ) equation by using the replica approach. The stationary state for the KPZ equation is realized by setting the initial condition the two-sided Brownian motion (BM) with respect to the space variable. Developing techniques for dealing with this initial condition in the replica analysis, we elucidate some exact nature of the height fluctuation for the KPZ equation. In particular, we obtain an explicit…

Large deviations for the KPZ equation from the KP equation

Height Fluctuations for the Stationary KPZ Equation

Reflected Brownian Motions in the KPZ Universality Class
A system of asymmetrically reflected Brownian motions is studied under various initial conditions. Asymmetric reflection means that each particle is reflected from its left neighbor. This system can

This work presents results from extensive numerical integration of the Kardar-Parisi-Zhang equation in 1+1 dimensions aimed to check the long-time behavior of the dynamical structure factor of the KPZ system and gives an analytic expression that yields a very good approximation to the numerical data.

Our previous work on the one-dimensional KPZ equation with sharp wedge initial data is extended to the case of the joint height statistics at n spatial points for some common fixed time. Assuming a
