Continuous collective strong coupling between atoms and a high finesse optical cavity
Julia R. K. Cline, Vera M. Schäfer, Zhijing Niu +3
We demonstrate continuous loading of strontium atoms into a high finesse ring cavity and observe continuous strong collective coupling in the form of a vacuum Rabi splitting betwee…
An atomic array optical clock with single-atom readout
Ivaylo S. Madjarov, Alexandre Cooper, Adam L. Shaw +5
Currently, the most accurate and stable clocks use optical interrogation of either a single ion or an ensemble of neutral atoms confined in an optical lattice. Here, we demonstrate…
Atomic clock performance beyond the geodetic limit
W. F. McGrew, X. Zhang, R. J. Fasano +9
The passage of time is tracked by counting oscillations of a frequency reference, such as Earth's revolutions or swings of a pendulum. By referencing atomic transitions, frequency…
Faraday-shielded, DC Stark-free optical lattice clock
K. Beloy, X. Zhang, W. F. McGrew +7
We demonstrate the absence of a DC Stark shift in an ytterbium optical lattice clock. Stray electric fields are suppressed through the introduction of an in-vacuum Faraday shield.…
Hyperpolarizability and operational magic wavelength in an optical lattice clock
R. C. Brown, N. B. Phillips, K. Beloy +11
Optical clocks benefit from tight atomic confinement enabling extended interrogation times as well as Doppler- and recoil-free operation. However, these benefits come at the cost o…
Ultra-stable optical clock with two cold-atom ensembles
M. Schioppo, R. C. Brown, W. F. McGrew +10
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation…
