Bose-Einstein condensation of alkaline earth atoms: ;{40}Ca.
We have achieved Bose-Einstein condensation of ;{40}Ca, the first for an alkaline earth element. The influence of elastic and inelastic collisions associated with the large ground-state s-wave scattering length of ;{40}Ca was measured. From these findings, an optimized loading and cooling scheme was developed that allowed us to condense about 2 x 10;{4} atoms after laser cooling in a two-stage ...
متن کاملOn the Bose–Einstein condensation of exotic atoms
The scattering length for hydrogenic atoms with variable lepton mass, ranging from H to pμ, is calculated. The non-trivial sensitivity of the scattering length to non-adiabatic effects is investigated using the coupled-channel approach. The physical conditions for the Bose–Einstein condensation of exotic atoms are expressed in terms of this scattering length, which for the pμ atoms interacting ...
متن کاملBose-Einstein condensation of atoms in a uniform potential.
We have observed the Bose-Einstein condensation of an atomic gas in the (quasi)uniform three-dimensional potential of an optical box trap. Condensation is seen in the bimodal momentum distribution and the anisotropic time-of-flight expansion of the condensate. The critical temperature agrees with the theoretical prediction for a uniform Bose gas. The momentum distribution of a noncondensed quan...
متن کاملBose-Einstein condensation of atoms in a trap.
We point out that the local density approximation (LDA) of Oliva is an adaptation of the Thomas-Fermi method, and is a good approximation when ε = ¯ hω/kT << 1. For the case of scattering length a > 0, the LDA leads to a quantitative result (14') easily checked by experiments. Critical remarks are made about the physics of the many body problem in terms of the scattering length a.

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Thesis directed by Prof. Eric Cornell Bose-Einstein condensates in dilute atomic gases have been around for almost 5 years now. The first experiments dealt with density related properti...
