Which kind of systems can be considered long range ?

Bruno Marcos

à 11h en salle C. Brot

There are many systems which present long range interactions, such gravitational ones, two-dimensional vortices, cold atoms, etc. In this talk, I will start explaining the scenario of their evolution, which consists first in the generic formation of out-of-equilibrium long lived states, called "Quasi Stationary States" and then a (comparatively) very slow relaxation towards thermal equilibrium. Studying then the characteristic time of both processes, I will give a classification of interactions according to their dynamical properties, which differs from the (usual) one according to their thermal equilibrium ones.
