Sr lattice clock with inaccuracy below 10
Martin M. Boyd, Andrew D. Ludlow, Sebastian Blatt +4
Aided by ultra-high resolution spectroscopy, the overall systematic uncertainty of the - clock resonance for lattice-confined Sr has been characterized…
Optical atomic coherence at the one-second time scale
Martin M. Boyd, Tanya Zelevinsky, Andrew D. Ludlow +4
Highest resolution laser spectroscopy has generally been limited to single trapped ion systems due to rapid decoherence which plagues neutral atom ensembles. Here, precision spectr…
Narrow Line Photoassociation in an Optical Lattice
T. Zelevinsky, M. M. Boyd, A. D. Ludlow +5
With ultracold Sr in a 1D magic wavelength optical lattice, we performed narrow line photoassociation spectroscopy near the SP intercombination transition.…
Systematic study of the Sr clock transition in an optical lattice
Andrew D. Ludlow, Martin M. Boyd, T. Zelevinsky +5
With ultracold Sr confined in a magic wavelength optical lattice, we present the most precise study (2.8 Hz statistical uncertainty) to-date of the - optical…
A high-accuracy optical clock via three-level coherence in neutral bosonic Sr
Robin Santra, Ennio Arimondo, Tetsuya Ido +2
An optical atomic clock scheme is developed that utilizes two lasers to establish coherent coupling between the ground state of Sr and the first excit…
Precision spectroscopy and density-dependent frequency shifts in ultracold Sr
Tetsuya Ido, Thomas H. Loftus, Martin M. Boyd +3
By varying the density of an ultracold Sr sample from cm to cm, we make the first definitive measurement of the density-related frequency sh…
