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…
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…
A clock network for geodesy and fundamental science
C. Lisdat, G. Grosche, N. Quintin +32
Leveraging the unrivaled performance of optical clocks in applications in fundamental physics beyond the standard model, in geo-sciences, and in astronomy requires comparing the fr…
Determination of the Boltzmann constant by laser spectroscopy as a basis for future measurements of the thermodynamic temperature
Cyril Lemarchand, Khelifa Djerroud, Benoît Darquié +6
In this paper, we present the latest results on the measurement of the Boltzmann constant kB, by laser spectroscopy of ammonia at 10 ?m. The Doppler absorption profile of a ro-vibr…
Measurement of the Boltzmann constant by the Doppler broadening technique at a 3,8x10-5 accuracy level
Khelifa Djerroud, Cyril Lemarchand, Alexandre Gauguet +7
In this paper, we describe an experiment performed at the Laboratoire de Physique des Lasers and dedicated to an optical measurement of the Boltzmann constant. With the proposed in…
Absolute frequency measurements for hyperfine structure determination of the R(26) 62-0 transition at 501.7 nm in molecular iodine
Andrei Goncharov, Olivier Lopez, Anne Amy +1
The absolute frequencies of the hyperfine components of the R(26) 62-0 transition in molecular iodine at 501.7 nm are measured for the first time with an optical clockwork based on…
