New measurement of the transition frequency of hydrogen: contribution to the proton charge radius puzzle
Hélène Fleurbaey, Sandrine Galtier, Simon Thomas +6
We present a new measurement of the two-photon transition frequency of hydrogen, realized with a continuous-wave excitation laser at 205 nm on a room-temperature atomic bea…
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…
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…
An experimental study of intermodulation effects in an atomic fountain frequency standard
Jocelyne Guéna, Gregor Dudle, Pierre Thomann
The short-term stability of passive atomic frequency standards, especially in pulsed operation, is often limited by local oscillator noise via intermodulation effects. We present a…
Atomic Parity Violation : Principles, Recent Results, Present Motivations
Jocelyne Guéna, Michel Lintz, Marie-Anne Bouchiat
We review the progress made in the determination of the weak charge, Q\_w, of the cesium nucleus which raises the status of Atomic Parity Violation measurements to that of a precis…
Measurement of the parity violating 6S-7S transition amplitude in cesium achieved within 2 \times 10^{-13} atomic-unit accuracy by stimulated-emission detection
J. Guéna, M. Lintz, M. -A. Bouchiat
We exploit the process of asymmetry amplification by stimulated emission which provides an original method for parity violation (PV) measurements in a highly forbidden atomic trans…
