Abstract: In this talk I will question the validity of the continuum limit and the use of frozen N-body realizations to obtain qualitative information on particle orbits in large N gravitational system in stellar dynamics. With the aid of detailed numerical simulations with refined symplectic integrators developed in the context of numerical celestial mechanics, I will compare orbits in frozen potentials with orbits in self consistent equilibrium models. In addition, I will show some results that could be relevant for the physics of charged particle beams. Read more
