Sr optical clock with systematic uncertainty and measurement of its absolute frequency with uncertainty
T. Lindvall, T. Fordell, K. J. Hanhijärvi +4
We report on a Sr single-ion optical clock with an estimated fractional systematic uncertainty of . The low uncertainty is enabled by small rf loss…
Noise-induced servo errors in optical clocks utilizing Rabi interrogation
T. Lindvall, A. E. Wallin, K. J. Hanhijärvi +1
We show that in optical clocks based on Rabi interrogation, both laser-frequency and magnetic-field flicker () noise with zero mean can lead to servo errors at the …
Evaluation of a Sr optical clock with a direct measurement of the blackbody radiation shift and determination of the clock frequency
M. Steinel, H. Shao, M. Filzinger +7
We report on an evaluation of an optical clock that uses the transition of a single Sr ion as the reference. In con…
High-Accuracy Determination of Paul-Trap Stability Parameters for Electric-Quadrupole-Shift Prediction
T. Lindvall, K. J. Hanhijärvi, T. Fordell +1
The motion of an ion in a radiofrequency (rf) Paul trap is described by the Mathieu equation and the associated stability parameters that are proportional to the rf and dc electric…
Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
The spin resonance clock transition of the endohedral fullerene
R. T. Harding, S. Zhou, J. Zhou +6
The endohedral fullerene has narrow electron paramagnetic resonance lines which have been proposed as the basis for a condensed-matter portable atomic cloc…
