Monte Carlo simulation of relative diffusion in stochastic fields

A model of charged particles in turbulent clumps has been investigated using Monte Carlo simulations. In the white noise case, the results of the present simulations on diffusion confirm the scaling property proposed by one of the authors (M.S.). In the colored noise case, an efficient method to generate correlated fields is presented, and thereby the role of colored noise in diffusion is clarified by studying a qualitative change from diffusion under white noise to diffusion under colored noise.
