The unit of time: present and future directions
S. Bize
Some 50~years ago, physicists, and after them the entire world, started to found their time reference on atomic properties instead of motions of the Earth that have been in use sin…
First international comparison of fountain primary frequency standards via a long distance optical fiber link
J. Guéna, S. Weyers, M. Abgrall +25
We report on the first comparison of distant caesium fountain primary frequency standards (PFSs) via an optical fiber link. The 1415 km long optical link connects two PFSs at LNE-S…
Optical to microwave clock frequency ratios with a nearly continuous strontium optical lattice clock
Jérôme Lodewyck, Sławomir Bilicki, Eva Bookjans +10
Optical lattice clocks are at the forefront of frequency metrology. Both the instability and systematic uncertainty of these clocks have been reported to be two orders of magnitude…
Development of a strontium optical lattice clock for the SOC mission on the ISS
S. Origlia, S. Schiller, M. S. Pramod +25
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests…
Comparing a mercury optical lattice clock with microwave and optical frequency standards
R Tyumenev, M Favier, S Bilicki +9
In this paper we report the evaluation of an optical lattice clock based on neutral mercury down to a relative uncertainty of . Comparing this characterized fre…
Atomic fountains and optical clocks at SYRTE: status and perspectives
M. Abgrall, B. Chupin, L. De Sarlo +9
In this article, we report on the work done with the LNE-SYRTE atomic clock ensemble during the last 10 years. We cover progress made in atomic fountains and in their application t…
