Progress on Optical Clock Technology for Operational Timescales
S. Peil, W. Tobias, J. Whalen +2
While optical clock technology has advanced rapidly in recent years, incorporating the technology into operational timescales has progressed more slowly. The highest accuracy frequ…
Cold Beam Optical Clock with Multifrequency Spectroscopy
William G. Tobias, Bryan Hemingway, Steven Peil
We demonstrate an optical clock based on Ramsey-Bordé interferometry in a laser-cooled Ca beam. The mean velocity is reduced by an order of magnitude relative to a thermal…
Tellurium Spectrometer for Transitions in Strontium and Other Alkaline-Earth Atoms
T. G. Akin, Bryan Hemingway, Steven Peil
We measure the spectrum of tellurium-130 in the vicinity of the 461~nm cycling transition in neutral strontium, a popular element for atomic clock…
Competition between Factors Determining Bright versus Dark Atomic States within a Laser Mode
Bryan Hemingway, T. G. Akin, Steven Peil +1
We observe bimodal fluorescence patterns from atoms in a fast atomic beam when the laser excitation occurs in the presence of a magnetic field and the atoms sample only a portion o…
Vapor-cell frequency reference for short-wavelength transitions in neutral calcium
Jennifer Taylor, Bryan Hemingway, James Hanssen +2
We have characterized the molecular tellurium (Te) spectrum in the vicinity of the 423nm and the 431nm transitions in neutral calcium. These transit…
Dynamic response of a spin-1/2 Kondo singlet
Bryan Hemingway, Stephen Herbert, Michael Melloch +1
We present a study of spin 1/2 Kondo singlets in single electron transistors under a microwave frequency bias excitation. We compare time-averaged conductance to predicted univ…
