چکیده
Bose-Einstein condensation (BEG) of atoms with attractive mteractions i:< profoundly different from BEC of atoms with repulsive interactions. \Ye describe expenments with Bose condensates of 'Li atoms ..•...hich are weakJy attracting at uJ· tralaw temperature. We measure the distribution of condensate occupation numbers occurring in the gas using a near-resonant optical probe to image the atom doud. This data shows that the number is limited and demonstrates the dynamics of condensate growth and collapse due to the attractive interactions.

Manipulating Bose-Einstein condensates with laser light
A dilute gas Bose-Einstein condensate was probed and manipulated by off-resonant laser beams. Spontaneous and stimulated off-resonant light scatterings were studied experimentally. Stimulated, two-photon Bragg scattering was used for spectroscopic measurement of the mean-field energy and of the intrinsic momentum uncertainty of the condensate. The high momentum and energy resolution of this met...
متن کاملSuperradiant rayleigh scattering from a bose-einstein condensate
Rayleigh scattering off a Bose-Einstein condensate was studied. Exposing an elongated condensate to a single off-resonant laser beam resulted in the observation of highly directional scattering of light and atoms. This collective light scattering is caused by the coherent center-of-mass motion of the atoms in the condensate. A directional beam of recoiling atoms was built up by matter wave ampl...
متن کاملIncoherent scattering of light by a Bose – Einstein condensate of interacting atoms
We demonstrate that incoherent photon scattering by a Bose–Einstein condensate of non-ideal atomic gas is enhanced due to bosonic stimulation of spontaneous emission, similarly to coherent scattering in forward direction. Necessary initial population of non-condensate states is provided by quantum depletion of a condensate caused by interatomic repulsion. Since the most reliable methods of diag...
متن کاملNear-resonant spatial images of confined Bose-Einstein condensates in a 4-Dee magnetic bottle
We present quantitative measurements of the spatial density profile of Bose-Einstein condensates of sodium atoms confined in a 4-Dee magnetic bottle. The condensates are imaged in transmission with near-resonant laser light. We demonstrate that the Thomas-Fermi surface of a condensate can be determined to better than 1%. More generally, we obtain excellent agreement with mean-field theory. We c...
متن کاملStrongly enhanced inelastic collisions in a Bose–Einstein condensate near Feshbach resonances
The properties of Bose–Einstein condensed gases can be strongly altered by tuning the external magnetic field near a Feshbach resonance. Feshbach resonances affect elastic collisions and lead to the observed modification of the scattering length. However, as we report here, this is accompanied by a strong increase in the rate of inelastic collisions. The observed three–body loss rate in a sodiu...
