1. 1. Bose-Einstein Condensate Jets from Different Traps

   Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Emmanuel-Roosevelt D Costa; [2022]
   Nyckelord :Bose-Einstein Condensate; Jets; Bose Fireworks; Gross-Pitaevskii equation; Physics and Astronomy;

   Sammanfattning : This thesis presents a numerical study of the emission of jets by a trapped Bose-Einstein Condensate (BEC). The Gross-Pitaevskii equation is used for the simulation of this phenomenon. When the scattering length of a trapped BEC is periodically modulated it emits jets of matter. LÄS MER
