AbstractThe chaotic diffusion in velocity space has been studied by numerically solving the motion equation of charged particles in the wave field with different kinds of wave phase spectra and analytically calculating the correlation functions. It is found that the diffusion in velocity space strongly depends on the wave phase spectrum. For the periodic spectrum with two different phases, the small relative phase makes the diffusion deviate from the quasi-linear one even for an arbitrarily large overlap parameter. The quasi-linear approximation is valid when the overlap parameter is large for the spectrum in which the wave phases of any group of three neighboring waves are different. The quasi-linear threshold can be much larger than the one of the zero phased standard mapping. Published by AIP Publishing.
