This article aims to study the time fractional coupled nonlinear Schrödinger equation, which explains the interaction between modes in nonlinear optics and Bose-Einstein condensation. The proposed generalized projective Riccati equation method and modified auxiliary equation method extract a more efficient and broad range of soliton solutions. These include novel solutions like a combined dark-lump wave soliton, multiple dark-lump wave soliton, two dark-kink solitons, flat kink-lump wave, multiple U-shaped with lump wave, combined bright-dark with high amplitude lump wave, bright-dark with lump wave and kink dark-periodic solitons are derived. The travelling wave patterns of the model are graphically presented with suitable parameters in 3D, density, contour and 2D surfaces, enhancing understanding of parameter impact. The proposed model's dynamics were observed and presented as quasi-periodic chaotic, periodic systems and quasi-periodic. This analysis confirms the effectiveness and reliability of the method employed, demonstrating its applicability in discovering travelling wave solitons for a wide range of nonlinear evolution equations.
本文旨在研究时间分数阶耦合非线性薛定谔方程,该方程解释了非线性光学和玻色-爱因斯坦凝聚中模式之间的相互作用。所提出的广义投影黎卡提方程方法和修正辅助方程方法提取了更高效、更广泛的孤子解。这些解包括新颖的解,如组合暗孤子波、多暗孤子波、两个暗扭子、平扭孤子、多 U 形带孤子、组合亮暗带大振幅孤子、亮暗带孤子和扭子暗周期孤子。模型的行波模式以合适的参数在 3D、密度、等高线和 2D 表面上以图形方式呈现,增强了对参数影响的理解。观察并呈现了所提出模型的动力学为拟周期混沌、周期系统和拟周期系统。该分析证实了所采用方法的有效性和可靠性,表明其在发现广泛的非线性演化方程中的行波孤子方面的适用性。
