Data-driven estimation of optical soliton solutions with time-dependent variable coefficients for the nonlinear Schrödinger equation
摘要
This study investigates the propagation and dynamics of optical waves governed by the variable-coefficient nonlinear Schrödinger equation. As a fundamental model in nonlinear wave theory, the NLSE plays a pivotal role in describing wave phenomena across diverse fields, including nonlinear optics, quantum mechanics, and fluid dynamics. Its ability to capture the interplay between dispersion and nonlinearity makes it indispensable for modeling localized wave structures, such as solitons, rogue waves, and breathers, which are critical to understanding complex wave behavior in real-world systems. Wave dynamics, including rogue waves, need to be studied to keep people safe in the ocean and to understand how they work, which helps protect marine ecosystems and make good use of ocean resources. Using the well-known enhanced modified simple equation method, we are trying to trace specific solutions that explain basic wave patterns realized in nature and the experimental phenomena, such as optical solitons, Bose–Einstein condensates, and Plasma waves. This method uses the improved modified simple equation to address the variable-coefficient nonlinear Schrödinger equation. The enhanced modified simple equation method uses a traveling wave variable called
