Noise, discreteness effects and the continuum limit in N-body systems, revisited #
By means of active and frozen N-Body simulations we revise the role of discreteness effects and external noise in the dynamics of self gravitating systems and non-neutral plasmas. In particular, we show that the use of frozen N-body realization may, in certain cases, lead to misleading conclusions.
