BRIGHT SOLITON DYNAMICS OF ONE-DIMENSIONAL QUANTUM SYSTEM WITH HIGHER-ORDER NONLINEAR INTERACTION AND DISPERSION EFFECTS

We investigate the typical quantum systems that are modeled by the (1+1)-dimensional Schrodinger equation, which contains third-order and fourth-order dispersion eects, higher-order scattering effects and cubic-quintic-septic nonlinear interaction. By using the F-expansion method, we solvethis higher-order Schrodinger equation, identifying the bright soliton solution under appropriate system settings. The bright soliton features are shown by exact numerical evaluation, followed by analytical features derivation at the boundaries of the bright soliton wave form, demonstrating the applicability of the theoretical treatment presented in this study.
