Nonquasilinear evolution of particle velocity in incoherent waves with random amplitudes
arXiv:0803.3962 · doi:10.1016/j.cnsns.2008.05.014
Abstract
The one-dimensional motion of particles in the field of many incoherent waves is revisited numerically. When the wave complex amplitudes are independent, with a gaussian distribution, the quasilinear approximation is found to always overestimate transport and to become accurate in the limit of infinite resonance overlap.
