Stochastic solution framework for the resonance nonlinear Schrödinger model via Brownian motion process

Despite substantial research into nonlinear Schrödinger equation equations, present techniques frequently tackle resonant nonlinear dynamics and stochastic perturbations separately, limiting comprehension of their combined impact on wave propagation. In this paper, we address this gap by creating a unified computational framework for the stochastic resonance nonlinear Schrödinger equation, a model that captures the interaction of nonlinear wave dynamics, resonant interactions, and ambient noise. The suggested unified techniques allow for the creation of novel stochastic wave structures. These solutions are essential for accurately capturing the influence of environmental noise and random perturbations on nonlinear wave dynamics, thereby providing a more realistic description of resonance, stability, and energy transfer mechanisms. They also offer deeper insight into noise-induced phenomena, such as stochastic resonance, modulation instability, and the formation of complex wave structures, which cannot be explained by deterministic models alone. We further demonstrate how variations in the physical parameters and the stochastic noise term systematically influence the behavior of the proposed solutions. The proposed techniques provide a generalizable framework for future analytical and computational studies of stochastic nonlinear partial differential equations.
