Abstract

Molecular Dynamics (MD) method is used to simulate a dusty plasma system as a one component plasma (OCP).  The heavy dust particles are considered as discrete particles interacting with each other through the Yukawa potential. This assumption is justified by the screening effect due to the lighter plasma components (electrons and ions). Solitons excitation at different values of the Coulomb coupling parameter (?) is simulated. The formation of solitons in the system using electric field pulse in a narrow region is studied. Different scenarios of the interaction of solitons are studied for: A) Two solitons with the same amplitude and opposite directions.  B) Two solitons with different amplitudes and opposite directions.  C) Two solitons with different amplitudes and propagating in the same direction.
