We perform numerical simulations of the Gross-Pitaevskii equation for harmonically trapped systems in the presence of dark and grey solitons, and we compare them with analytical solutions derived for homogeneous condensates. Our numerical results show a very good agreement with the theory in the limit of large trapped systems, which are available in current experiments5 p.application/pdfengcc-by-nc-nd (c) Bravo, 2016http://creativecommons.org/licenses/by-nc-nd/3.0/es/Condensació de Bose-EinsteinSolitonsTreballs de fi de grauBose-Einstein condensationSolitonsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
