Pierwszy polski kondensat Bosego-Einsteina

A team working in the new Polish National Laboratory for Atomic, Molecular and Optical Physics obtained the first Polish Bose-Einstein condensate of 87 Rb atoms in a magnetic trap. The paper describes the experimental approach as well as the first observations, and discusses the very special methodology of ultra-low-temperature physics.

/sup 85/rubidium-a Bose-Einstein condensate with adjustable interactions

Carl Wieman, Jacob Roberts, Simon L. Cornish +2 more

Summary form only given. For most values of magnetic field, very cold /sup 85/Rb atoms have a large negative scattering length and large loss rates from magnetic traps. The latter makes it difficult to cool the atoms low enough to achieve Bose-Einstein condensation (BBC), while the former constrains the size of a possible BEC to <100 atoms. However, we have found that near the Feshbach resonance at 154 G the loss rates decrease substantially, and the scattering length can be made positive. We have used these two features to create condensates of several thousand atoms in /sup 85/Rb. We are then able to study the dynamics and loss processes of these condensates as we vary the magnetic field. Small changes in magnetic field give rise to large changes in the magnitude and sign of the self-interaction in the condensate as well as possible couplings to molecular condensates. We will discuss the wide range of behaviors we have observed in this interesting system.

Bose-Einstein Condensation in a Quadrupole-Ioffe Configuration Trap

Tilman Esslinger, Immanuel Bloch, Theodor W. Hänsch

We demonstrate Bose-Einstein condensation of rubidium atoms in a simple low-power magnetic trap. This trap combines the quadrupole with the Ioffe configuration ~QUIC trap! and consists of just three coils. Magneto-optically trapped Rb atoms are first loaded into the linear trapping potential of a magnetic quadrupole, which is then converted into the parabolic geometry of an Ioffe trap. During this process two spherical quadrupole traps with perpendicular axes merge and the trapped atomic cloud moves close to the magnetic field producing coils, resulting in tight confinement of the atoms while the power dissipation of the trap remains low. The magnetically trapped atoms are cooled to below the phase transition of Bose-Einstein condensation by rf-induced evaporation. @S1050-2947~98!51210-3#
