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…
Testing local position and fundamental constant invariance due to periodic gravitation and boost using long-term comparison of the SYRTE atomic fountains and H-masers
M. E. Tobar, P. L. Stanwix, J. J. McFerran +8
The frequencies of three separate Cs fountain clocks and one Rb fountain clock have been compared to various hydrogen masers to search for periodic changes correlated with the chan…
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…
An Alkali-Vapor Cell with Metal Coated Windows for Efficient Application of an Electric Field
David Sarkisyan, A. S. Sarkisyan, Jocelyne Guéna +2
We describe the implementation of a cylindrical T-shaped alkali-vapor cell for laser spectroscopy in the presence of a longitudinal electric field. The two windows are used as two…
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…
