We consider a single component and a binary mixture as well. Using a two-mode ansatz, we obtain the corre-sponding equations of motion from the Gross-Pitaevskii equation. We investigate the Josephson dynamics and the macroscopic quantum self-trapping regimes for the single component case. On the other hand, for the binary mixture, we explore the small oscillations for the strongly polarized and the non-polarized case5 p.application/pdfengcc-by-nc-nd (c) Ristol, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Condensació de Bose-EinsteinInteraccions febles (Física nuclear)Treballs de fi de grauBose-Einstein condensationWeak interactions (Nuclear physics)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
