Pure Quartic Solitons

DOI

Supervisors: Martijn de Sterke, Andrea Blanco Redondo
Institution: University of Sydney

A research project done as part of the Talented Student Program at the University of Sydney. This paper is the core thing this project is planning to explore.

Goal

The goal of this project is to produce a numerical, soliton-like solution for the differential equation:

\frac{\partial A}{\partial z} =
		i \frac{\beta_4}{24} \frac{\partial^4 A}{\partial t^4} +
		i \gamma_{eff} {\left|A\right|}^{2} A

This is much harder than it sounds, since it essentially resolves to being a boundary value problem with 8 real parameters (4 complex parameters), but it can be reduced to 3 real parameters through a bunch of clever tricks. Similarly, the search can be constrained using further tricks. And finally, it all boils down to a bruteforce of the search space.
