Random Field Kac Model: From Micro to Macro Structures

vendredi 21 janvier 2011, 11h00 - 12h00

Salle de réunion, espace Turing

I present some results on equilibrium and non equilibrium statistical mechanics
setting for Kac Ising spin systems with random external field emphasizing relations with variational continuum models and PDE.
Materials exhibiting a fine mixture of phases are familiar and well studied phenomenon in many settings. Such mixtures can arise for a variety of reasons.
I focus here on those materials where the presence of the impurities causes the
microscopic structure to vary from point to point and my attempt is to emphasize
contiguity with different areas, like variational calculus, PDE, probability and
Statistical Mechanics. An essential point in the whole approach is the use of both
microscopic and macroscopic description in capturing the physical phenomena.

This talk is going to take place in the room « LEDUC » located at the ground floor in the main building. To find the room take the corridor on the right just after the main entrance. The room is on the left half way down the corridor.
