Cooling atomic motion with quantum interference
Open accessAbstract
We theoretically investigate the quantum dynamics of the center of mass of trapped atoms, whose internal degrees of freedom are driven in a $\ensuremath{\Lambda}$-shaped configuration with the lasers tuned at two-photon resonance. In the Lamb-Dicke regime, when the motional wave packet is well localized over the laser wavelength, transient coherent population trapping occurs, canceling transitions at the laser frequency. In this limit the motion can be efficiently cooled to the ground state of the trapping potential. We derive an equation for the center-of-mass motion by adiabatically eliminating the internal degrees of freedom. This treatment provides the theoretical background of the scheme presented in [G. Morigi et al., Phys. Rev. Lett. 85, 4458 (2000)] and implemented in [C.F. Roos et al., Phys. Rev. Lett. 85, 5547 (2000)]. We discuss the physical mechanisms determining the dynamics and identify parameters regimes, where cooling is efficient. We discuss implementations of the scheme to cases where the trapping potential is not harmonic.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Not all ions are visible in the associated camera images due to the finite size of the detection laser beam.
“Not all ions are visible in the associated camera images due to the finite size of the detection laser beam [32].”
From Individual-Ion Addressing and Readout in a Penning Trap (2024) · cites this paper as [32]
Section II discusses a trapped ion’s laser-driven motion, and the Conclusions describe a theoretical cooling analysis; neither addresses camera images or ions outside a detection beam. Searches for camera visibility, imaging, and detection-beam size found no passage supporting the claim. Page numbers were not available in our copy. (LLM, conf=0.72)

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.
