Envelop solitons in dusty plasmas for warm dust

Characteristics of nonlinear dust acoustic waves in a Lorentzian dusty plasma with effect of adiabatic and nonadiabatic grain charge fluctuation

“…[13][14][15][16][17] Extensive theoretical studies have also been reported on several cases of nonlinear propagation of dust acoustic and dust ion acoustic waves considering fixed as well as fluctuating gain charges, in case of Maxwellian plasmas. [18][19][20][21][22][23][24][25][26] Space and astrophysical plasmas consist of charged dust particles whose existence was proved by space craft observation. [27][28][29][30][31] Such plasmas consist of suprathermal charge particles whose velocities follow the generalized kappa distribution 32 and is known as Lorentzian dusty plasma.…”

Dust acoustic solitary waves in dusty plasma with nonthermal ions

“…Cylindrical KP equation in warm dusty plasmas with two ions has been studied (Wang and Zhang 2006). Solitary waves of the KdV equation have been investigated in dusty plasmas with variable dust charge in Duan et al (2003), Zhang and Xue (2005). Pakzad and Javidan (2009) have also analyzed solitons of the KP equation for these plasmas with two temperature ions.…”

Conservation law and exact solutions for ion acoustic waves in a magnetized quantum plasma

“…(19) and (20) are separated according to different combination of derivatives of ϕ (2) ξ and ϕ (2) η and after some simplification following system of equations for α and λ are obtained,…”

“…In dusty plasma, there are essential two types of acoustic waves: high frequency dust ion acoustic wave (DIAWs) involving mobile ions and static dust grains, and a low frequency dust acoustic wave (DAWs) involving mobile dust grains. Both modes have been studied theoretically and experimentally [1][2][3][4][5][6][7][8][9]. Dusty Plasmas are present in astrophysical and space environments, like the tails of comets, interstellar medium and planetary rings [4][5].…”
