Abstract
In the present work, we have investigated the effect of trapping as a microscopic phenomenon on the propagation of 1 and 2D linear and nonlinear quantum drift ion acoustic waves in a spatially inhomogeneous degenerate electron-positron-ion plasma in the presence of quantizing magnetic field having degenerate electrons and positrons. We derive the linear dispersion relation and nonlinear Korteweg-deVries and Kadomtsev Petviashvili equation for drift ion acoustic waves. It is observed that the characteristics of the dispersion relation and nonlinear drift ion solitary structures have been modified significantly by the positron concentration and quantizing magnetic field. The work presented here may be beneficial to understand the propagation of drift solitary structures in dense astrophysical environments and in intense-laser plasma interactions.
