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…
Frequency Shifts due to Stark Effects on a Rb two-photon transition
Kyle W Martin, Benjamin Stuhl, Jon Eugenio +4
The two-photon transition in Rb is of interest for the development of a compact optical atomic clock. Here we present a rigorous calculation of the 7…
Compact Optical Atomic Clock Based on a Two-Photon Transition in Rubidium
Kyle W. Martin, Gretchen Phelps, Nathan D. Lemke +7
Extra-laboratory atomic clocks are necessary for a wide array of applications (e.g. satellite-based navigation and communication). Building upon existing vapor cell and laser techn…
Ex Vacuo Atom Chip Bose-Einstein Condensate (BEC)
Matthew B. Squires, Spencer E. Olson, Brian Kasch +5
Ex vacuo atom chips, used in conjunction with a custom thin walled vacuum chamber, have enabled the rapid replacement of atom chips for magnetically trapped cold atom experiments.…
Tunable axial potentials for atom chip waveguides
James A. Stickney, Brian Kasch, Eric Imhof +4
We present a method for generating precise magnetic potentials that can be described by a polynomial series along the axis of a cold atom waveguide near the surface of an atom chip…
Collisional decoherence in trapped atom interferometers that use non-degenerate sources
James A. Stickney, Matthew B. Squires, James Scoville +2
The coherence time, and thus sensitivity, of trapped atom interferometers that use non-degenerate gasses are limited by the collisions between the atoms. An analytic model that des…
