Abstract

We use a pseudo-spectral Fast Fourier Transform method on MATLAB to study solitary wave solutions for fractional, coupled non-linear Schrödinger equations and find novel stability boundaries associated with solution symmetry within the fractional derivative order. From the bifurcation diagram we find soliton stability corresponding to symmetry, and other curious dynamics such as, symmetry breaking, non-stationary, and bright / dark pulses, and potentially new conditions to support symmetry making dynamics. We explore fractional derivatives of order α ∈ (1, 2], and display the results for consideration.

KeywordsFractional derivative, coupled non-linear Schrödinger equation, MATLAB, soliton, symmetry, dark/bright solitons
