Cubic-quartic optical solitons and conservation laws with cubic-quintic-septic-nonic and quadrupled-power law nonlinearities

Abstract

The focus of this paper is the retrieval of cubic-quartic optical solitons with quadrupled power and nonlinearity governed by cubic-quintic-septic-nonic laws. The enhanced Kudryashov’s approach retrieved the full spectrum of solitons. Subsequently, the method of multipliers revealed the conservation laws corresponding to the two models.
