Collisional relaxation of long range interacting systems of particles

Abstract

Systems of particles with long range interactions present two phases in their evolution: first, the formation of Quasi-Stationary states (such as galaxies) in a process called violent relaxation and, second, the much slower relaxation towards thermal equilibrium, in a process called colli-sional relaxation. In this contribution we focus on the last process and we present the first exact calculations of diffusion coefficients performed for non-homogeneous configurations.
