We study solitary wave interactions in the Euler–Poisson equations modeling ion acoustic plasmas and their approximation by KdV n-solitons. Numerical experiments are performed and solutions compared to appropriately scaled KdV n-solitons. While largely correct qualitatively the soliton solutions did not accurately capture the scattering shifts experienced by the solitary waves. We propose corre...

A perpendicular ion drift is investigated as a mechanism for the generation of magnetic field structures in a highly collisional dusty plasma. The basic dissipation mechanism is assumed to be the dustneutrals momentum exchange, so that plasmas with a small ionization fraction are natural candidates for experiments. The model reduces to a nonlinear partial differential equation for the vector po...

We introduce a signal processing approach to compensate for the timingjitter produced by the acoustic effect in soliton communications. The other main sources of timing jitter, the Gordon-Haus effect and the polarization effect, are inherently stochastic. By contrast, the acoustic effect is deterministic and becomes the dominant source of bit error rates in standard soliton systems when the bit...

Article history: Received 23 May 2011 Accepted 6 June 2011 Available online 14 June 2011 Communicated by V.M. Agranovich Dust heating in dusty plasmas due to thermal electric field fluctuations and dust acoustic waves is examined. It is shown that dust particles acquire large random motion in fluctuating electric fields (within dust cloud) of background plasma causing dust electrostatic pressur...
