Propagation of Sound in Two-Species Bose-Einstein Condensates
D. Lima, P. Borckmans, G. Dewel
We investigate the propagation of zero sound in two-species interpenetrating Bose-Einstein condensates. In very elongated clouds, this propagation is shown to be essentially one-di…

Fringe patterns of Bose condensates
S. Metens, D. Lima, P. Borckmans +1
We investigate within the Gross-Pitaevski (GP) theory the formation of fringe patterns between two Bose condensates stored in a double well potential modelling the forces applied t…
