Optical closed form soliton structures for the Kuralay-II equation in nonlinear optical complex media

This article investigates the optical soliton solutions for the Kuralay-IIA equation using the analytical approach. This model has a wide scope in the fields of nonlinear optics, proving gauge equivalency among different models, the motion of integrating space curves, and ferromagnetic materials. To find the exact solutions, the kuralay-IIA equation is first converted into an ODE by using wave transformations. These solutions are extracted by using the modified exponential rational function (MERF) method which provided us with the different types of solitons such as dark, singular, complex dark-singular, solitary wave, and exponential function solutions. To provide insight into the physical behaviors of the nonlinear Kuralay IIA equation, some of the selected solutions are visualized through 3-D surface plots, line graphs, and contour plots.
