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…
Laser spectroscopy with nanometric gas cells : distance dependence of atom-surface interaction and collisions under confinement
Ismahène Hamdi, Petko Todorov, Alexander Yarovitski +11
The high sensitivity of Laser Spectroscopy has made possible the exploration of atomic resonances in newly designed "nanometric" gas cells, whose local thickness varies from 20nm t…
A Bose-Einstein condensate bouncing off a rough mirror
Hélène Perrin, Yves Colombe, Brigitte Mercier +2
We present experimental results and theoretical analysis of the diffuse reflection of a Bose-Einstein condensate from a rough mirror. The mirror is produced by a blue-detuned evane…
Absolute frequency measurement of an SF6 two-photon line using a femtosecond optical comb and sum-frequency generation
Anne Amy-Klein, Andrei Goncharov, Mickael Guinet +4
We demonstrate a new simple technique to measure IR frequencies near 30 THz using a femtosecond (fs) laser optical comb and sum-frequency generation. The optical frequency is direc…
Diffraction of a Bose-Einstein Condensate in the Time Domain
Yves Colombe, Brigitte Mercier, Hélène Perrin +1
We have observed the diffraction of a Bose-Einstein condensate of rubidium atoms on a vibrating mirror potential. The matter wave packet bounces back at normal incidence on a blue-…
Long-distance frequency dissemination with a resolution of 10-17
Christophe Daussy, Olivier Lopez, Anne Amy-Klein +11
We use a new technique to disseminate microwave reference signals along ordinary optical fiber. The fractional frequency resolution of a link of 86 km in length is 10-17 for a one…
