Precision Metrology Meets Cosmology: Improved Constraints on Ultralight Dark Matter from Atom-Cavity Frequency Comparisons
Colin J. Kennedy, Eric Oelker, John M. Robinson +6
We conduct frequency comparisons between a state-of-the-art strontium optical lattice clock, a cryogenic crystalline silicon cavity, and a hydrogen maser to set new bounds on the c…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Demonstration of a time scale based on a stable optical carrier
William R. Milner, John M. Robinson, Colin J. Kennedy +13
We demonstrate a time scale based on a phase stable optical carrier that accumulates an estimated time error of ps over 34 days of operation. This all-optical time scale…
JILA SrI Optical Lattice Clock with Uncertainty of
Tobias Bothwell, Dhruv Kedar, Eric Oelker +5
We report on an improved systematic evaluation of the JILA SrI optical lattice clock, achieving a nearly identical systematic uncertainty compared to the previous strontium accurac…
Optical clock intercomparison with precision in one hour
E. Oelker, R. B. Hutson, C. J. Kennedy +14
Improvements in atom-light coherence are foundational to progress in quantum information science, quantum optics, and precision metrology. Optical atomic clocks require local oscil…
Collective atomic scattering and motional effects in a dense coherent medium
Sarah L. Bromley, Bihui Zhu, Michael Bishof +9
We investigate collective emission from coherently driven ultracold Sr atoms. We perform two sets of experiments, using a strong and weak transition that are insensitive…
