Abstract:
This dissertation explores various solutions to nonlinear reaction–diffusion systems, focusing primarily on the nonlinear Schr\u00f6dinger equation. Three types of solutions are investigated: radial solutions (with no angular dependence), vortex solutions (with angular dependence but no phase dependence), and spiral solutions (which depend on phase). The study considers both free particles without potential and trapped particles inside the cylindrical potential with an impenetrable barrier. We show that spiral solutions to the nonlinear Schr\u00f6dinger equation only exist for a constant phase. Furthermore, we show that the spiral solutions to the nonlinear Schr\u00f6dinger equation amount to solving a system of nonlinear ordinary differential equations. This system is shown to be a special case of the $\\lambda$–$\\omega$ reaction–diffusion system.<\/p>\n","protected":false},"excerpt":{"rendered":"
