Data for Generalized Gross-Pitaevskii equation for 2D bosons with attractive interactions

The dataset contains data related to the publication "Generalized Gross-Pitaevskii Equation for 2D Bosons with Attractive Interactions" by Michał Suchorowski, Fabian Brauneis, Hans-Werner Hammer, Michał Tomza, and Artem G. Volosniev, accepted for publication in Physical Review Letters (DOI: https://doi.org/10.1103/2831-t3jk). Data was produced using the own developed code, available publicly (DOI: 10.5281/zenodo.17593676). The zip file contains the source data for the figures in the associated publication. The data consists of the model's parameters and observables obtained by numerically solving the extended Gross-Pitaevskii equation for the two-dimensional attractive Bose-Einstein condensate. The description of each data file's structure can be found in the README file.
