Collision of Bose-Einstein Condensates*

We study the collision of two interacting Bose-Einstein Condensates of ⁸⁷RB and ⁴¹K in a weak harmonic confinement. The study is performed by means of numerical solution of two coupled Gross Pitaevskii equations. The process is investigated in presence of both attractive and repulsive interaction between the two atomic components, showing various complex phenomena such as the formation of dark and bright solitons, condensate trapping, and coupled oscillations of boson populations.
