Degenerate Bose-Bose mixture in a three-dimensional optical lattice
Open accessAbstract
We produce a heteronuclear quantum degenerate mixture of two bosonic species, $^{87}\mathrm{Rb}$ and $^{41}\mathrm{K}$, in a three-dimensional optical lattice. On raising the lattice barriers, we observe the disappearance of the inference pattern of the heavier $^{87}\mathrm{Rb}$, shifting toward shallower lattice depths in the presence of a minor fraction of $^{41}\mathrm{K}$. This effect is sizable and requires only a marginal overlap between the two species. We compare our results with similar findings reported for Fermi-Bose mixtures and discuss the interpretation scenarios proposed to date, arguing that the explanation may be linked to the increased effective mass due to the interspecies interactions.

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.
