Microwave-dressed state-selective potentials for atom interferometry
V. Guarrera, R. Szmuk, J. Reichel +1
We propose a novel and robust technique to realize a beam splitter for trapped Bose-Einstein condensates (BECs). The scheme relies on the possibility of producing different potenti…
Demonstration of a Dual Alkali Rb/Cs Atomic Fountain Clock
J. Guéna, P. Rosenbusch, Ph. Laurent +7
We report the operation of a dual Rb/Cs atomic fountain clock. 133Cs and 87Rb atoms are cooled, launched, and detected simultaneously in LNE-SYRTE's FO2 double fountain. The dual c…
Extended coherence time on the clock transition of optically trapped Rubidium
G. Kleine Büning, J. Will, W. Ertmer +6
Optically trapped ensembles are of crucial importance for frequency measurements and quantum memories, but generally suffer from strong dephasing due to inhomogeneous density and l…
Spin self-rephasing and very long coherence times in a trapped atomic ensemble
Christian Deutsch, Fernando Ramirez-Martinez, Clement Lacroûte +7
We perform Ramsey spectroscopy on the ground state of ultra-cold 87Rb atoms magnetically trapped on a chip in the Knudsen regime. Field inhomogeneities over the sample should limit…
AC Stark shift of the Cs microwave atomic clock transitions
P. Rosenbusch, S. Ghezali, V. A. Dzuba +3
We analyze the AC Stark shift of the Cs microwave atomic clock transition theoretically and experimentally. Theoretical and experimental data are in a good agreement with each othe…
