Head on collision between two different kinds of nonlinear waves in a dusty plasma lattice chain

Abstract The paper investigates the violation of the linear superposition principle during the head-on collision of nonlinear waves in dusty plasma lattices. It is important for advancing our understanding of wave interactions in complex systems, which is critical for optimizing experimental setups in plasma physics and materials science. The study uses numerical simulations and molecular dynamics to analyze the collision between KdV solitons and bright envelope waves. Key findings include the violation of linear superposition, with the amplitude ratio during the collision being highly sensitive to system parameters. This discovery helps refine predictive models for wave dynamics in nonlinear media. The research also offers valuable insights into soliton fusion. The findings offer significant implications for wave dynamics in plasma physics and materials science.
