Feedback control of collapse-induced turbulent condensation of Langmuir waves

Feedback control of collapse-induced turbulent condensation of Langmuir waves

Feedback control of collapse-induced turbulent condensation in a dissipative open Langmuir wave system governed by a two-dimensional generalized nonlinear Schrödinger equation is investigated numerically by following the evolution of an initial disturbance. It is found that with self-regulated feedb...

Zusammenfassung:Feedback control of collapse-induced turbulent condensation in a dissipative open Langmuir wave system governed by a two-dimensional generalized nonlinear Schrödinger equation is investigated numerically by following the evolution of an initial disturbance. It is found that with self-regulated feedback control the wavelength of the asymptotic turbulent condensate can, to a certain degree, be controlled.
