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…
Symmetric micro-wave potentials for interferometry with thermal atoms on a chip
M. Ammar, M. Dupont-Nivet, L. Huet +8
A trapped atom interferometer involving state-selective adiabatic potentials with two microwave frequencies on a chip is proposed. We show that this configuration provides a way to…
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…
Experimenting an optical second with strontium lattice clocks
R. Le Targat, L. Lorini, Y. Le Coq +17
Progress in realizing the SI second had multiple technological impacts and enabled to further constraint theoretical models in fundamental physics. Caesium microwave fountains, rea…
Critical rotation of a harmonically trapped Bose gas
P. Rosenbusch, D. S. Petrov, S. Sinha +5
We study experimentally and theoretically a cold trapped Bose gas under critical rotation, i.e. with a rotation frequency close to the frequency of the radial confinement. We ident…
