Ultra cold atoms and Bose-Einstein condensation for quantum metrology

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 ...

On 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 ...

Bose-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...
