An electron–positron pair plasma having dust impurity and density non-uniformity is studied for its unperturbed state and evolution of solitary structures under the effect of either positively charged or negatively charged dust grains. Zeroth-order

Considering a homogenous positron-electron pair plasma, we investigate the propagating and growing modes in the plasma under the presence of heavy dust particles that are negatively charged. Since these dust grains are massive particles, they do not

A viable scheme of THz radiation generation by beating of two lasers ( ω1, k→1; ω2, k→2) in a nanotube array, mounted on a dielectric substrate, is proposed and studied. The free electrons of the nanotubes acquire a large oscillatory velocity a

A scheme of terahertz (THz) generation, using nonlinear mixing of two color laser (fundamental ω1 and slightly frequency shifted second harmonic ω2) in clustered plasma, is investigated. The lasers exert ponderomotive force on cluster electrons and

Solitary waves in a weakly relativistic electron-positron (e-p) plasmas having negatively charged dust grains are investigated by employing a fluid model. It is found that fast and slow modes are possible in such a plasma that correspond to the propa

A theoretical investigation concerning the propagation of compressive solitons in a plasma comprising electrons, positrons, and dust grains is presented by considering the dust grains of either positive charge or negative charge. Using reductive pert

We consider an electron-positron pair plasma that has negatively charged dust grains. Being the same mass of the electrons and positrons, both of these species contribute to the wave excitation in the plasma. Since the frequency of oscillations is hi
