Data and Code for "Modulational instability and numerically persistent solitary waves in a fractional Gross-Pitaevskii model with nonlocal interactions"

This record provides the Data and Code package for the revised manuscript "Modulational instability and numerically persistent solitary waves in afractional Gross-Pitaevskii model with nonlocal interactions", submitted to Chaos, Solitons and Fractals. The package contains processed numerical data, figure-generation scripts, figures, algorithm-parameter settings, Python requirements, and reproducibilityinstructions. The files support the modulational-instability diagnostics, stationary-branch computations, Krein/VK index checks, grid and time-stepconvergence tests, conservation-error diagnostics, perturbation-amplitude tests, long-time propagation evidence, and persistence-map visualizationsreported in the revised manuscript. The package is intended to improve transparency and reproducibility of the numerical results. It does not contain raw experimental data.
