Observing spin-squeezed states under spin-exchange collisions for a second
Meng-Zi Huang, Jose Alberto de la Paz, Tommaso Mazzoni +5
Using the platform of a trapped-atom clock on a chip, we observe the time evolution of spin-squeezed hyperfine clock states in ultracold rubidium atoms on previously inaccessible t…
Spontanous spin squezing in a rubidium BEC
Théo Laudat, Vincent Dugrain, Tommaso Mazzoni +5
We describe an experiment where spin squeezing occurs spontaneously within a standard Ramsey sequence driving a two-component Bose-Einstein condensate (BEC) of 87Rb atoms trapped i…
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…
Millimeter-long Fiber Fabry-Perot cavities
Konstantin Ott, Sebastien Garcia, Ralf Kohlhaas +4
We demonstrate fiber Fabry-Perot (FFP) cavities with concave mirrors that can be operated at cavity lengths as large as 1.5mm without significant deterioration of the finesse. This…
Atomic fountains and optical clocks at SYRTE: status and perspectives
M. Abgrall, B. Chupin, L. De Sarlo +9
In this article, we report on the work done with the LNE-SYRTE atomic clock ensemble during the last 10 years. We cover progress made in atomic fountains and in their application t…
Stability of a trapped atom clock on a chip
Ramon Szmuk, Vincent Dugrain, Wilfried Maineult +2
We present a compact atomic clock interrogating ultracold 87Rb magnetically trapped on an atom chip. Very long coherence times sustained by spin self-rephasing allow us to interrog…
