Studying a dual-species BEC with tunable interactions
S. B. Papp, J. M. Pino, C. E. Wieman
We report on the observation of controllable spatial separation in a dual-species Bose-Einstein condensate (BEC) with Rb and Rb. Interparticle interactions between th…
Heteronuclear molecules in an optical dipole trap
J. J. Zirbel, K. -K. Ni, S. Ospelkaus +6
We report on the creation and characterization of heteronuclear KRb Feshbach molecules in an optical dipole trap. Starting from an ultracold gas mixture of K-40 and Rb-87 atoms, we…
Experiments in Dilute Atomic Bose-Einstein Condensation
Eric A. Cornell, Jason R. Ensher, Carl E. Wieman
Both theoretical and experimental activity in BEC has expanded dramatically in the three years since the first observation of BEC in a dilute atomic gas. One is tempted to ask, why…
Having it Both Ways: Distinguishable Yet Phase-Coherent Mixtures of Bose-Einstein Condensates
E. A. Cornell, D. S. Hall, M. R. Matthews +1
We have begun a series of experiments on mixed bosonic quantum fluids. Our system is mixed Bose-Einstein condensates in dilute Rb-87. By simultaneously trapping the atoms in two di…
