Nonlinear Schroedinger equation for dispersive media
Journal Article
·
· Phys. Rev. Lett.; (United States)
A self-consistent three-dimensional nonlinear Schroedinger equation is derived for dispersive media such as plasmas by using the Krylov-Bogoliubov-Mitropolsky multiple space-time method. The necessary and sufficient conditions for the occurrence of modulational instability and the collapse of Langmuir as well as ion-acoustic waves are obtained. In weakly turbulent systems, collapse is not possible.
