Stochastic diffusion of electrons in evolutive Langmuir fields

The stochastically diffusive processes of electrons in the spatiotemporally complicated Langmuir fields, which are directly simulated by the cubicquintic nonlinear Schroedinger equation (NSE), and solitary envelope fields are investigated, respectively. It is shown that the diffusion of the low velocity particles is a very important mechanism for energy being transformed from the region low velocity to the region of high velocity. (orig.)
