Scaling laws for the non-linear coupling constant of a Bose-Einstein condensate at the threshold of delocalization
Scaling laws the non-linear coupling constant Bose-Einstein condensate threshold of delocalization
2012/2/28
We explore the localization of a quasi-one-, quasi-two-, and three-dimensional ultra-cold gas by a finite-range defect along the corresponding 'free'-direction/s. The time-independent non-linear Schro...
Bose-Einstein condensate in gases of rare atomic species
Bose-Einstein condensate gases of rare atomic species Atomic Physics

Abstract: We report on the successful extension of production of Bose-Einstein Condensate (BEC) to rare species. Despite its low natural abundance of 0.13%, $^{168}$Yb is directly evaporatively cooled...
Accurate control of a Bose-Einstein condensate by managing the atomic interaction
Bose-Einstein condensate atomic interaction
2010/4/2
We exploit the variation of the atomic interaction in order to move ultra-cold atoms across an AC-driven periodic lattice. By breaking relevant symmetries, a gathering of atoms is achieved. Accurate c...
In this work, we examine a system for coherent transfer of atoms into a Bose-Einstein condensate. We utilize two spatially separate Bose-Einstein condensates in different hyperfine ground states held ...
