A Variational Characterization of a Gibbs Measure related to the Aviles-Giga Functional
Jean-Dominique Deuschel, Clara Thierbach, Barbara Zwicknagl
We derive explicit characterizations of Gibbs-measures related to the Aviles-Giga functional. We build on the variational approach presented by Barashkov and Gubinelli (2020) in th…

Scaling Limits of Line Models in Degenerate Environment
Jean-Dominique Deuschel, Henri Elad Altman
We consider a 2-dimensional model of random walk in random environment known as line model. The environment is described by two independent families of i.i.d. random variables dict…

Gradient estimates of the heat kernel for random walks among time-dependent random conductances
Jean-Dominique Deuschel, Takashi Kumagai, Martin Slowik
In this paper we consider a time-continuous random walk in in a dynamical random environment with symmetric jump rates to nearest neighbours. We assume that these ra…
