We have shown that depending on the form of the imprinted phase step, the soliton bends and then, via a snake instability, it decays into vortices. We have performed numerical simulations of the time evolution of the imprinted dark soliton in two-dimensions. Finally, we have qualitatively interpreted the theoretical framework that describes this phenomenon in the approximation of weakly interacting bosons5 p.application/pdfengcc-by-nc-nd (c) Pascual, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/SolitonsCondensació de Bose-EinsteinTreballs de fi de grauSolitonsBose-Einstein condensationBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
