THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar:  

Collisional relaxation of systems of particles with long range interactions 

Prof. Bruno Marcos

Université de Nice – Sophia Antipolis – França 

Abstract: 

There are many systems which present long range interactions, such gravitational systems, 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. Then, I will focus on two topics related to the second

part of the evolution: (i) the existence of Quasi Stationary States depending of the range of the interaction and (ii) the validity of the Chandrasekhar approximation in inhomogeneous systems.
