Modulational instability of dust-ion-acoustic waves and associated first and second-order rogue waves in super-thermal plasma

no code implementations11 Mar 2021 B. E. Sharmin, R. K. Shikha, N. K. Tamanna, N. A. Chowdhury, A. Mannan, A. A. Mamun

A proper theoretical research has been carried out to explore the modulational instability (MI) conditions of dust-ion-acoustic (DIA) waves (DIAWs) in a three-component dusty plasma system containing inertialess $\kappa$-distributed electrons, and inertial warm positive ions and negative dust grains.

Modulational instability of dust-ion-acoustic waves in pair-ion plasma having non-thermal non-extensive electrons

no code implementations3 Feb 2021 M. K. Islam, A. A. Noman, J. Akter, N. A. Chowdhury, A. Mannan, T. S. Roy, M. Salahuddin, A. A. Mamun

The MI growth rate and the configuration of the DIARWs are examined, and it is found that the MI growth rate increases (decreases) with increasing the number density of the negatively charged dust grains in the presence (absence) of the negative ions.

Ion-acoustic rogue waves in double pair plasma having non-extensive particles

no code implementations17 Dec 2020 S. Jahan, M. N. Haque, N. A. Chowdhury, A. Mannan, A. A. Mamun

The modulational instability (MI) of ion-acoustic (IA) waves (IAWs) and associated IA rogue waves (IARWs) in double pair plasma containing non-extensive electrons, iso-thermal positrons, negatively and positively charged ions have been governed by the standard nonlinear Schr\"{o}dinger equation (NLSE).
