AI总结:

该研究针对规范Fokas-Lenells方程,通过Hirota双线性方法求解孤子解,探讨色散效应变化对孤子动力学的影响,为非线性系统研究提供参考。

摘要:

Davydova-Lashkin-Fokas-Lenells方程(DLFLE)是Fokas-Lenells方程(FLE)的一种规范等价形式,同时考虑了时空色散(STD)和非线性色散(ND)效应。这两种效应之间的平衡产生孤子,由于其作为信息技术中信号载体的潜在应用性,一直是研究中有趣的话题。我们对色散效应引入了变化,并应用Hirota双线性方法来求解所提出的DLFLE的孤子解,探索孤子动力学如何随色散效应的变化而表现。所提出的方程适用于多种系统,如超短光脉冲、离子回旋等离子体波、在某些外部场下的玻色-爱因斯坦凝聚体(BEC)物质波孤子等。在变化效应下对这些系统的研究非常有限,我们希望我们的工作能帮助研究人员更深入地理解孤子动力学,并在各种其他非线性领域中研究变化效应下的问题。

英文摘要:

Davydova-Lashkin-Fokas-Lenells equation (DLFLE) is a gauged equivalent form of Fokas-Lenells equation (FLE) that addresses both spatio-temporal dispersion (STD) and nonlinear dispersion (ND) effects. The balance between those effects results a soliton which has always been an interesting topic in research due to its potential applicability as signal carrier in information technology. We have induced a variation to the dispersion effects and apply Hirota bilinear method to realise soliton solution of the proposed DLFLE and explore how the soliton dynamic behaves in accordance to the variation of the dispersion effects. The proposed equation is applicable for number of systems like ultrashort optical pulse, ioncyclotron plasma wave, Bose-Einstein condensate (BEC) matter-wave soliton under certain external fields, etc. The study on such systems under varying effects is very limited and we hope our work can benefit the researchers to understand soliton dynamics more and work on various other nonlinear fields under varying effects.
