Dual-species Bose-Einstein condensate ofRb87andCs133
Open accessAbstract
We report the formation of a dual-species Bose-Einstein condensate of $^{87}\mathrm{Rb}$ and $^{133}\mathrm{Cs}$ in the same trapping potential. Our method exploits the efficient sympathetic cooling of $^{133}\mathrm{Cs}$ via elastic collisions with $^{87}\mathrm{Rb}$, initially in a magnetic quadrupole trap and subsequently in a levitated optical trap. The two condensates each contain up to $2\ifmmode\times\else\texttimes\fi{}{10}^{4}$ atoms and exhibit a striking phase separation, revealing the mixture to be immiscible due to strong repulsive interspecies interactions. Sacrificing all the $^{87}\mathrm{Rb}$ during the cooling, we create single-species $^{133}\mathrm{Cs}$ condensates of up to $6\ifmmode\times\else\texttimes\fi{}{10}^{4}$ atoms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
