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.
本研究考察了在白噪声影响下随机广义沙梅尔(GS)模型孤立波解的动力学特性。通过运用波变换技术,我们推导了控制随机方程,并使用辅助方程法分析其孤立解。该研究通过解析和数值方法研究了不同噪声强度对孤子行为的影响。数值模拟表明,孤子在低噪声水平下保持其特征形状,但随着噪声强度增加,其调制程度越来越高,最终导致失稳。这些发现在量子力学、等离子体物理和非线性光学等领域具有重要意义,在这些领域中,理解噪声环境下的孤子行为对于实际应用至关重要。结果突出了非线性系统中孤子与噪声之间复杂的相互作用,其中小扰动可显著改变系统动力学。此外,强调了孤子稳定性对诸如波速和噪声强度等模型参数的敏感性。这些发现为噪声环境下孤子的行为提供了有价值的见解,并为孤子稳定性的未来研究,特别是在不同随机条件下的研究,提出了潜在的途径。未来的研究可以探索不同类型的随机过程,如有色噪声或 Lévy 噪声,对孤子动力学的影响。
