High-Resolution Magnetometry with a Spinor Bose-Einstein Condensate
Open accessAbstract
We demonstrate a precise magnetic microscope based on direct imaging of the Larmor precession of a $^{87}\mathrm{Rb}$ spinor Bose-Einstein condensate. This magnetometer attains a field sensitivity of $8.3\text{ }\text{ }\mathrm{pT}/{\mathrm{Hz}}^{1/2}$ over a measurement area of $120\text{ }\text{ }\ensuremath{\mu}{\mathrm{m}}^{2}$, an improvement over the low-frequency field sensitivity of modern SQUID magnetometers. The achieved phase sensitivity is close to the atom shot-noise limit, estimated as $0.15\text{ }\text{ }\mathrm{pT}/{\mathrm{Hz}}^{1/2}$ for a unity duty cycle measurement, suggesting the possibilities of spatially resolved spin-squeezed magnetometry. This magnetometer marks a significant application of degenerate atomic gases to metrology.

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.
