Variational calculation of diffusion coefficients in stochastic lattice gases Chikashi Arita (Universität des Saarlandes, Saarbrücken) Deriving macroscopic behaviors from microscopic dynamics of particles   is a fundamental problem. In stochastic lattice gases one tries to  demonstrate this hydrodynamic limit. The evolution of a stochastic   lattice gas with symmetric hopping rules is described by a diffusion   equation […]

On the hydrodynamic behaviour of interacting lattice gases far from equilibrium Alexandre Lazarescu (Centre de Physique Théorique, École Polytechnique) Lattice gases are a particularly rich playground to study the large scale emergent behaviour of microscopic models. A few things are known in general for models that are sufficiently close to equilibrium (i.e. with rates close
