waves is analyzed in detail. The effects of different ranges of the nonextensive parameter q on the

MI are studied. The growth rate of the MI is also given for different values of the q parameter...

Schrödinger equation (NLSE) which governs the modulational instability (MI) of the DIAWs is obtained. Modulational instability regions and the growth rate of nonlinear waves are discussed. It is shown that the wave characters are affected by the value...

and the modulational instability of dust ion acoustic waves is analyzed. Parametric investigations indicate that the presence of superthermal distributed electrons significantly modify the modulational instability and its growth rate. The effect of particle relative...

In this theoretical study, based on a nonlinear wave equation describing the interaction of fields of an X-ray laser beam with relativistic quantum plasma, modulation instability and formation of solitary waves are investigated. Analytical...
