Bose-Einstein condensation in a robust microtrap -- the combination of wire traps and atom chips
In the presented work, we report about the successful creation of a Rubidium Bose-Einstein condensate. We use so called magnetic wire traps, which are especially simple, as they consist out of a wire and a homogeneous bias field. These wire traps are especially suited for Bose-Einstein condensation. Furthermore complex trapping potentials to manipulate a Bose-Einstein condensate can be realized. We combine 'large' and small scale wire traps. The 'large' scale is realized with a massive copper structure, while for the small wire traps we use the so called atom chip. This combination is promising, because it allowed us to develop a condensation process in the copper structure, which is independent of the structures on the atom chip, and thus the exchange of the 'physics' area. First experiments with the Bose-Einstein condensate are presented and discussed in detail.
