Measuring ion oscillations at the quantum level with fluorescence light
G. Cerchiari, G. Araneda, L. Podhora +3
We demonstrate an optical method for detecting the mechanical oscillations of an atom with single-phonon sensitivity. The measurement signal results from the interference between t…
Ion-trap electrode preparation with Ne bombardment
K. S. McKay, D. A. Hite, Y. Colombe +7
We describe an ex-situ surface-cleaning procedure that is shown to reduce motional heating from ion-trap electrodes. This precleaning treatment, to be implemented immediately befor…
A stable fiber-based Fabry-Perot cavity
T. Steinmetz, A. Balocchi, Y. Colombe +4
We report the development of a fiber-based, tunable optical cavity with open access. The cavity is of the Fabry-Perot type and is formed with miniature spherical mirrors positioned…
Diffuse reflection of a Bose-Einstein condensate from a rough evanescent wave mirror
Helene Perrin, Yves Colombe, Brigitte Mercier +2
We present experimental results showing the diffuse reflection of a Bose-Einstein condensate from a rough mirror, consisting of a dielectric substrate supporting a blue-detuned eva…
A ring trap for ultracold atoms
Olivier Morizot, Yves Colombe, Vincent Lorent +2
We propose a new kind of toroidal trap, designed for ultracold atoms. It relies on a combination of a magnetic trap for rf-dressed atoms, which creates a bubble-like trap, and a st…
