Modulational instability of acoustic waves in a dusty plasma with nonthermal electrons and trapped ions
(Pergamon-Elsevier Science Ltd, 2019-04)
In the present work, employing the nonlinear field equations of a hot dusty plasma in the presence of nonthermal electrons and trapped ions, we studied the amplitude modulation of nonlinear waves in such a plasma medium ...
Analytical and numerical aspects of the dissipative nonlinear Schrödinger equation
(Işık University Press, 2016-02-15)
In this paper various analytical and numerical aspects of the dissipative nonlinear Schrodinger equation (d-NLS equation) are discussed. Decaying solitary wave type solutions derived by Demiray is reviewed and a new ...
Modulational instability of three dimensional waves in a plasma with vortex electron distribution
