39K Bose-Einstein condensate with tunable interactions.
We produce a Bose-Einstein condensate of 39K atoms. Condensation of this species with a naturally small and negative scattering length is achieved by a combination of sympathetic cooling with 87Rb and direct evaporation, exploiting the magnetic tuning of both inter- and intraspecies interactions at Feshbach resonances. We explore the tunability of the self-interactions by studying the expansion...
متن کاملStable Rb Bose-Einstein Condensates with Widely Tunable Interactions
Bose-Einstein condensation has been achieved in a magnetically trapped sample of Rb atoms. Long-lived condensates of up to 10 atoms have been produced by using a magnetic-field-induced Feshbach resonance to reverse the sign of the scattering length. This system provides many unique opportunities for the study of condensate physics. The variation of the scattering length near the resonance has b...
متن کاملStable 85Rb bose-einstein condensates with widely tunable interactions
Bose-Einstein condensation has been achieved in a magnetically trapped sample of 85Rb atoms. Long-lived condensates of up to 10(4) atoms have been produced by using a magnetic-field-induced Feshbach resonance to reverse the sign of the scattering length. This system provides new opportunities for the study of condensate physics. The variation of the scattering length near the resonance has been...
متن کاملDouble species Bose-Einstein condensate with tunable interspecies interactions.
We produce Bose-Einstein condensates of two different species, 87Rb and 41K, in an optical dipole trap in proximity of interspecies Feshbach resonances. We discover and characterize two Feshbach resonances, located around 35 and 79 G, by observing the three-body losses and the elastic cross section. The narrower resonance is exploited to create a double species condensate with tunable interacti...
متن کاملCollapse of Bose-Einstein condensates with dipole-dipole interactions
Bose-Einstein condensation of dilute trapped atomic gases @1,2# essentially depends on the interparticle interactions. In most experiments so far the dominated interactions have been short-range van der Waals forces which are characterized by the s-wave scattering length a. Spatially homogeneous condensates with positive scattering length ~repulsive interaction! are stable while condensates wit...
