Dust ion acoustic waves with Cairns–Tsallis electrons in the framework of KP-type equation

The features of dust ion acoustic waves (DIAWs) composed of cold ions, nonthermal nonextensive electrons as well as stationary dust particles are presented by KP-type equations. The effect of system parameters and higher order contributions on the phase velocity, amplitude and width of DIAWs is discussed. The parametric range for the existence of negative and positive solitons described by KP equation is presented. It is found that nonthermal and nonextensivity parameters and higher order contribution play a very crucial role in the formation of DIAWs. The results obtained would be valuable in interpreting certain nonlinear physical phenomena presented in the Earth's magnetosphere.
