Abstract

For systems modeled by the resonant nonlinear Schrödinger equation, we aim to investigate the soliton dynamics and the stability of the system. We extend the equation to a generalized form (GRD-NLSE) and utilize the modified F-expansion method to derive various soliton solutions, including bright, kink, and singular solitons for both (1 + 1)-dimensional and (2 + 1)-dimensional models. Additionally, we graphically illustrate soliton behavior. To analyze system stability, we perform modulation instability and soliton stability analyses. Our findings provide valuable guidance for experimental studies and observations of solitons in GRD-NLSE systems.

具有双幂律非线性的广义共振色散非线性薛定谔方程的光学孤子和调制不稳定性分析

对于以共振非线性薛定谔方程为模型的系统，我们旨在研究孤子动力学和系统的稳定性。我们将该方程扩展为广义形式（GRD-NLSE），并利用改进的 F 展开法推导出各种孤子解，包括 (1 + 1) 维和 (2 + 1) 维模型的亮孤子、扭结孤子和奇异孤子。此外，我们还以图表说明了孤子行为。为了分析系统稳定性，我们进行了调制不稳定性和孤子稳定性分析。我们的研究结果为 GRD-NLSE 系统中孤子的实验研究和观测提供了宝贵的指导。
