We consider invariant measures for the stochastic Burgers equation on $\mathbb{R}$, forced by the derivative of a spacetime-homogeneous Gaussian noise that is white in time and smooth in space. An invariant measure is indecomposable, or extremal, if it cannot be represented as a convex combination of other invariant measures. We show that for each $a\in\mathbb{R}$, there is a unique indecomposable law of a spacetime-stationary solution with mean $a$, in a suitable function space. We also show… 
Existence of stationary stochastic Burgers evolutions on $\mathbf{R}^2$ and $\mathbf{R}^3$
We prove that the stochastic Burgers equation on $\mathbf{R}^{d}$, $d<4$, forced by gradient noise that is white in time and smooth in space, admits spacetime-stationary solutions. These solutions
Invariant measures for stochastic conservation laws on the line
We consider a stochastic conservation law on the line with solution-dependent diffusivity, a super-linear, sub-quadratic Hamiltonian, and smooth, spatially-homogeneous kick-type random forcing. We
Viscous Shock Solutions to the Stochastic Burgers Equation
We define a notion of a viscous shock solution of the stochastic Burgers equation that connects "top" and "bottom" spatially stationary solutions of the same equation. Such shocks generally travel in
Localization of the continuum directed random polymer
. We consider the continuum directed random polymer (CDRP) model that arises as a scaling limit from 1 + 1 dimensional directed polymers in the intermediate disorder regime. We show that for a
Some recent progress on the stationary measure for the open KPZ equation
This note, dedicated in Harold Widom’s memory, is an expanded version of a lecture I gave in fall 2021 at the MSRI program “Universality and Integrability in Random Matrices and Interacting Particle
Gaussian fluctuations of replica overlap in directed polymers
. In this short note, we prove a central limit theorem for a type of replica overlap of the Brownian directed polymer in a Gaussian random environment, in the low temperature regime and in all
Existence of stationary ballistic deposition on the infinite lattice
A BSTRACT . Ballistic deposition is one of the many models of interface growth that are believed to be in the KPZ universality class, but have so far proved to be largely intractable mathematically.
Local KPZ behavior under arbitrary scaling limits
A BSTRACT . One of the main difficulties in proving convergence of discrete models of surface growth to the Kardar–Parisi–Zhang (KPZ) equation in dimensions higher than one is that the correct way to
Lyapunov exponents in a slow environment
Motivated by the evolution of a population in a slowly varying random environment, we consider the 1D Anderson model on finite volume, with viscosity κ > 0: ∂tu(t, x) = κ∆u(t, x) + ξ(t, x)u(t, x),


Exact lower-tail large deviations of the KPZ equation
Consider the Hopf--Cole solution $ h(t,x) $ of the KPZ equation with narrow wedge initial condition. Regarding $ t\to\infty $ as a scaling parameter, we provide the first rigorous proof of the Large
Invariant measures for stochastic partial differential equations in unbounded domains
We study stochastically forced semilinear parabolic partial differential equations of the Ginzburg-Landau type. The class of forcings considered are white noise in time and coloured smooth noise in
