Coarsening dynamics on with frozen vertices
Michael Damron, Sinziana M. Eckner, Hana Kogan +2
We study Markov processes in which -valued random variables , update by taking the value of a majority of their nearest neighbors or else tossing…
From normal diffusion to superdiffusion of energy in the evanescent flip noise limit
Cédric Bernardin, Patricia Gonçalves, Milton Jara +2
We consider a harmonic chain perturbed by an energy conserving noise depending on a parameter . When is of order one, the energy diffuses according to the standard heat equa…
Percolation and local isoperimetric inequalities
Augusto Teixeira
In this paper we establish some relations between percolation on a given graph G and its geometry. Our main result shows that, if G has polynomial growth and satisfies what we call…
Metastability of reversible random walks in potential fields
C. Landim, R. Misturini, K. Tsunoda
Let be an open and bounded subset of $\bb R^d$, and let $F:Ξ\to\bb R$ be a twice continuously differentiable function. Denote by th discretization of , $Ξ_N = Ξ\cap (N…
The Einstein relation for the KPZ equation
Patricia Gonçalves, Milton Jara
We compute the non-universal constants in the KPZ equation in one dimension, in terms of the thermodynamical quantities associated to the underlying microscopic dynamics. In partic…
Exclusion process with slow boundary
Rangel Baldasso, Otávio Menezes, Adriana Neumann +1
We study the hydrodynamic and the hydrostatic behavior of the Simple Symmetric Exclusion Process with \emph{slow boundary}. The term \emph{slow boundary} means that particles can b…
