Atomic clock frequency ratios with fractional uncertainty

Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24

We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and Sr. With total fractional uncertainties at or bel…

Optical Atomic Clock Comparison through Turbulent Air

Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32

We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…

Meta-study of laser power calibrations ranging 20 orders of magnitude with traceability to the kilogram

Paul A. Williams, Matthew T. Spidell, Joshua A. Hadler +11

Laser power metrology at the National Institute of Standards and Technology (NIST) ranges 20 orders of magnitude from photon-counting (1000 photons/s) to 100 kW (10^23 photons/s at…

Predictive Modeling of Cholera Outbreaks in Bangladesh

Amanda A. Koepke, Ira M. Longini, M. Elizabeth Halloran +2

Despite seasonal cholera outbreaks in Bangladesh, little is known about the relationship between environmental conditions and cholera cases. We seek to develop a predictive model f…
