Study on modes in a plasma having electrons, positrons and cold drifting ions

Dynamics of Dusty Pair-Ion-Electron Plasma Modeled by the Cylindrical Kadomtsev-Petviashvili Equations

“…In equilibrium state, there is no electrical field. Hence the total charge is neutral at equilibrium [14] and the Poisson equation becomes:…”

“…The electron-ion Plasma type exhibit a variety of collective modes due to large mass difference between the electron and the ion; whereas in pair-ion plasma, the masses are equal and the charges are opposite [1,2]. This pair-ion-plasma has been widely studied for the fundamental understanding of environment such as ionosphere, magnetosphere, quasars, etc [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Examples of such plasma are: Hydogen pair-ion plasma produce by catalytic ionization, electron-positron plasma produced by introducing electron in positron plasma, pair-ions plasma of fullerenes ± experimentally produced in laboratory through the impact ionization of fullerenes [3].…”

“…The study of dusty plasmas represents one of the most rapidly growing field of plasma physics [7][8][9][10][11]. Their theoretical features and applications observed in Earth magnetosphere, ionosphere, mesosphere, cometary tail, and planetary rings make them very attractive [12][13][14][15][16]. Various types of dusty pair-ion plasmas can be found both in space and in laboratory.…”
