Article: Optically Confined Bose–Einstein Condensates
[show abstract] [hide abstract]
ABSTRACT: With an optical dipole trap it is possible to confine Bose–Einstein condensates in different hyperfine states and in arbitrary magnetic bias fields, thus overcoming two major limitations of magnetic traps. In this review paper we characterize the properties of such a dipole trap and we summarize experiments which made use of the new experimental possibilities, including the reversible formation of a Bose–Einstein condensate, the observation of Feshbach resonances in sodium and the ground state properties of spinor Bose-Einstein condensates. Finally, we present some new results on the shape of magnetically trapped and ballistically expanding condensates.Journal of Low Temperature Physics 01/1998; 113(3):167-188. · 1.19 Impact Factor -
Article: Studies of Bose-Einstein Condensates
[show abstract] [hide abstract]
ABSTRACT: We review the recent achievements in observing Bose-Einstein condensation (BEC) in dilute atomic gases, and summarize our own studies of BEC in sodium. These include studies of static and dynamic behavior of the condensate and of its coherence properties.Journal of Low Temperature Physics 12/1997; 110(1):153-166. · 1.19 Impact Factor -
Article: Optical Confinement of a Bose-Einstein Condensate
[show abstract] [hide abstract]
ABSTRACT: Bose-Einstein condensates of sodium atoms have been confined in an optical dipole trap using a single focused infrared laser beam. This eliminates the restrictions of magnetic traps for further studies of atom lasers and Bose-Einstein condensates. More than five million condensed atoms were transferred into the optical trap. Densities of up to $3 \times 10^{15} cm^{-3}$ of Bose condensed atoms were obtained, allowing for a measurement of the three-body decay rate constant for sodium condensates as $K_3 = (1.1 \pm 0.3) \times 10^{-30} cm^6 s^{-1}$. At lower densities, the observed 1/e lifetime was more than 10 sec. Simultaneous confinement of Bose-Einstein condensates in several hyperfine states was demonstrated.
