Abstract

Our analysis suggests strongly that stationary pulses exist in nonlinear media with second-, third-, and fourth-order dispersion. A theory, based on the variational approach, is developed for finding approximate parameters of such solitons. It is obtained that the soliton velocity in the retarded reference frame can be different from the inverse of the group velocity of linear waves. It is shown that the interaction of the pulse spectrum with that of linear waves can affect the existence of stationary solitons. These theoretical results are supported by numerical simulations. Transformations between solitons of different systems are derived. A generalization for solitons in media with the highest even-order dispersion is suggested.

光学介质中的通用四次孤子

我们的分析强烈表明，在具有二阶、三阶和四阶色散的非线性介质中存在静止脉冲。我们基于变分法建立了一套理论，用于寻找此类孤子的近似参数。研究发现，孤子在迟滞参照系中的速度可能不同于线性波群速度的倒数。研究表明，脉冲频谱与线性波频谱的相互作用会影响静止孤子的存在。这些理论结果得到了数值模拟的支持。推导出了不同系统孤子之间的变换。提出了对具有最高偶阶色散的介质中的孤子的概括。美国物理学会出版 2024

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
