A new experiment to test parity symmetry in cold chiral molecules using vibrational spectroscopy
A Cournol, M. Manceau, M. Pierens +21
We present a brief review of our progress towards measuring parity violation in heavy-metal chiral complexes using mid-infrared Ramsey interferometry. We discuss our progress addre…
High-precision methanol spectroscopy with a widely tunable SI-traceable frequency-comb-based mid-infrared QCL
R. Santagata, D. Tran, B. Argence +14
There is an increasing demand for precise molecular spectroscopy, in particular in the mid-infrared fingerprint window that hosts a considerable number of vibrational signatures, w…
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…
