We consider a class of nearest-neighbor weakly asymmetric mass conservative particle systems evolving on $\mathbb{Z}$, which includes zero-range and types of exclusion processes, starting from a perturbation of a stationary state. When the weak asymmetry is of order $O(n^{-\gamma})$ for $1/2<\gamma\leq1$, we show that the scaling limit of the fluctuation field, as seen across process characteristics, is a generalized Ornstein-Uhlenbeck process. However, at the critical weak asymmetry when… 
On Microscopic Derivation of a Fractional Stochastic Burgers Equation
We derive, from a class of asymmetric mass-conservative interacting particle systems on $${\mathbb{Z}}$$Z, with long-range jump rates of order | · |−(1+α) for 0 < α < 2, different continuum
Derivation of the stochastic Burgers equation with Dirichlet boundary conditions from the WASEP
We consider the weakly asymmetric simple exclusion process on the discrete space $\{1,...,n-1\}$, in contact with stochastic reservoirs, both with density $\rho\in{(0,1)}$ at the extremity points,
Convergence to the Stochastic Burgers Equation from a degenerate microscopic dynamics
In this paper we prove the convergence to the stochastic Burgers equation from one-dimensional interacting particle systems, whose dynamics allow the degeneracy of the jump rates. To this aim, we
Stochastic Burgers equation from long range exclusion interactions
We consider one-dimensional exclusion processes with long jumps given by a transition probability of the form $p_n(\cdot)=s(\cdot)+\gamma_na(\cdot)$, such that its symmetric part $s(\cdot)$ is
On energy solutions to stochastic Burgers equation.
In this review we discuss the weak KPZ universality conjecture for a class of 1-d systems whose dynamics conserves one or more quantities. As a prototype example for the former case, we will focus on
Nonlinear Fluctuations of Weakly Asymmetric Interacting Particle Systems
We introduce what we call the second-order Boltzmann–Gibbs principle, which allows one to replace local functionals of a conservative, one-dimensional stochastic process by a possibly nonlinear
Nonlinear fluctuations of interacting particle systems
We introduce what we call the second-order Boltzmann-Gibbs principle, which allows to replace local functionals of a conservative, onedimensional stochastic process by a possibly nonlinear function
The infinitesimal generator of the stochastic Burgers equation
We develop a martingale approach for a class of singular stochastic PDEs of Burgers type (including fractional and multi-component Burgers equations) by constructing a domain for their infinitesimal
The KPZ Equation, Non-Stationary Solutions, and Weak Universality for Finite-Range Interactions
We study the weak KPZ universality problem by extending the KPZ universality results for weakly asymmetric exclusion processes to non-simple variants under deterministic initial data with constant

We study the stochastic six vertex model and prove that under weak asymmetry scaling (i.e., when the parameter $$\Delta \rightarrow 1^+$$ Δ → 1 + so as to zoom into the ferroelectric/disordered phase


Stochastic Burgers and KPZ Equations from Particle Systems
Abstract: We consider two strictly related models: a solid on solid interface growth model and the weakly asymmetric exclusion process, both on the one dimensional lattice. It has been proven that,

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
