Analysis of solitary wave behavior under stochastic noise in the generalized schamel equation

Abstract

Abstract This study investigates the dynamics of solitary wave solutions to the stochastic generalized Schamel (GS) model under the influence of white noise. By employing the wave transformation technique, we derive the governing stochastic equation and analyze its solitary solutions using the auxiliary equation method. The study examines the impact of varying noise intensities on the soliton’s behavior through both analytical and numerical approaches. Numerical simulations reveal that the soliton maintains its characteristic shape at low noise levels but becomes increasingly modulated as noise intensity increases, eventually leading to destabilization. These findings have significant implications in fields such as quantum mechanics, plasma physics, and nonlinear optics, where understanding soliton behavior in noisy environments is crucial for real-world applications. The results highlight the complex interplay between solitons and noise in nonlinear systems, where small perturbations can significantly alter the system’s dynamics. Furthermore, the sensitivity of the soliton’s stability to model parameters such as wave velocity and noise strength is emphasized. These findings provide valuable insights into the behavior of solitons in noisy environments and suggest potential avenues for future research on soliton stability, particularly under varying stochastic conditions. Future investigations could explore the effects of different types of stochastic processes, such as colored noise or Lévy noise, on soliton dynamics.
