摘要

研究考虑了无碰撞非磁化五成分尘埃等离子体,以研究木星环境中单质子和多质子面对面碰撞的意义、面对面碰撞引起的相移以及尘埃声波的不稳定性。为了研究面对面碰撞的后果,使用了扩展的 Poincaré-Lighthill-Kuo 方法来推导双面非线性 Korteweg-De Vries(KdV)方程。此外,为了研究尘埃声波的不稳定性,按照 Slathia 等人的方法推导出了非线性薛定谔方程。问题中的相关参数在相移(由面对面碰撞产生)、单、双、三和四倍孤子碰撞过程以及尘埃声孤子的产生中起着至关重要的作用。此外,等离子体参数对于暗孤子和包络冲击的形成也至关重要。

Instability analysis and face-to-face collision of dust acoustic waves in dusty plasmas: Perspective Jupiter environment

The collisionless unmagnetized five components dusty plasmas have been considered to study the significance of the face-to-face collision of single- and multi-solitons, phase shifts due to face-to-face collision, and instability of the dust acoustic waves in Jupiter's environment. To study the consequence of face-to-face collision extended Poincaré–Lighthill–Kuo method is used to derive the two-sided nonlinear Korteweg–De Vries (KdV) equation. Besides, to investigate the dust acoustic wave's instability, the nonlinear Schrödinger equation has been derived following the procedure of Slathia et al. The multi-soliton solutions are determined by employing the Hirota bilinear method. The concerned parameters in the issue play a crucial role in the phase shift (generated by the face-to-face collision); the collisional process of single-, double-, triple-, and quadruple-soliton; and the generation of dust acoustic solitons. Furthermore, the plasma parameters are crucial in the formation of dark solitons and envelop shocks.
