Electrostatic rogue waves in double pair plasmas

Abstract

A nonlinear Schrödinger equation is derived to investigate the modulational instability (MI) of ion-acoustic (IA) waves (IAWs) in a double pair plasma system containing adiabatic positive and negative ion fluids along with super-thermal electrons and positrons. The analytical analysis predicts two types of modes, viz. fast (${\omega }_f$) and slow (${\omega }_s$) IA modes. The possible stable and unstable parametric regions for the IAWs in presence of external perturbation can be observed for both ${\omega }_f$ and ${\omega }_s$. The number density of the negative ions and positrons play a vital role in generating the IA rogue waves (IARWs) in the modulationally unstable region. The applications of our present work in astrophysical environments [viz. D-region (${\mathrm{H}}^{+},{\mathrm{O}}_2^{-}$) and F-region (${\mathrm{H}}^{+},{\mathrm{H}}^{-}$) of the Earth's ionosphere] as well as in laboratory plasmas [viz. pair-ion Fullerene (${\mathrm{C}}^{+},{\mathrm{C}}^{-}$)] are pinpointed.
