We compute the one-point probability distribution for the stationary KPZ equation (i.e. initial data H(0,X)=B(X)$\mathcal {H}(0,X)=B(X)$, for B(X) a two-sided standard Brownian motion) and show that as time T goes to infinity, the fluctuations of the height function H(T,X)$\mathcal {H}(T,X)$ grow like T1/3 and converge to those previously encountered in the study of the stationary totally asymmetric simple exclusion process, polynuclear growth model and last passage percolation. The starting… 

Half-space stationary Kardar–Parisi–Zhang equation beyond the Brownian case

We study the Kardar–Parisi–Zhang (KPZ) equation on the half-line x ⩾ 0 with Neumann type boundary condition. Stationary measures of the KPZ dynamics were characterized in recent work: they depend on

Two-time height distribution for 1D KPZ growth: the recent exact result and its tail via replica

We consider the fluctuations in the stochastic growth of a one-dimensional interface of height $h(x,t)$ described by the Kardar-Parisi-Zhang (KPZ) universality class. We study the joint probability

Stochastic growth in time-dependent environments.

The Kardar-Parisi-Zhang (KPZ) growth equation in one dimension with a noise variance c(t) depending on time is studied and there is a transition at α=1/2, where the solution saturates at large times towards a nonuniversal limiting distribution.

Convergence of exclusion processes and the KPZ equation to the KPZ fixed point

We show that under the 1:2:3 scaling, critically probing large space and time, the height function of finite range asymmetric exclusion processes and the KPZ equation converge to the KPZ fixed point,

Large fluctuations of the KPZ equation in a half-space

We investigate the short-time regime of the KPZ equation in 1+11+1 dimensions and develop a unifying method to obtain the height distribution in this regime, valid whenever an exact solution exists

Aging for the stationary Kardar-Parisi-Zhang equation and related models

We study the aging property for stationary models in the KPZ universality class. In particular, we show aging for the stationary KPZ fixed point, the Cole-Hopf solution to the stationary KPZ

Time evolution of the Kardar-Parisi-Zhang equation

The use of the non-linear SPDEs are inevitable in both physics and applied mathematics since many of the physical phenomena in nature can be effectively modeled in random and non-linear way. The



Stationary Correlations for the 1D KPZ Equation

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

The Kardar-Parisi-Zhang Equation and Universality Class

Brownian motion is a continuum scaling limit for a wide class of random processes, and there has been great success in developing a theory for its properties (such as distribution functions or

Scaling Limit for the Space-Time Covariance of the Stationary Totally Asymmetric Simple Exclusion Process

The totally asymmetric simple exclusion process (TASEP) on the one-dimensional lattice with the Bernoulli ρ measure as initial conditions, 0<ρ<1, is stationary in space and time. Let Nt(j) be the
