Measuring densities of cold atomic clouds smaller than the resolution limit
Andrea Litvinov, Pierre Bataille, Etienne Maréchal +4
We propose and demonstrate an experimental method to measure by absorption imaging the size and local column density of a cloud of atoms, even when its smallest dimension is smalle…
Adiabatic spin-dependent momentum transfer in an SU(N) degenerate Fermi gas
P. Bataille, A. Litvinov, I. Manai +7
We introduce a spin-orbit coupling scheme, where a retro-reflected laser beam selectively diffracts two spin components in opposite directions. Spin sensitivity is provided by swee…
Cooling All External Degrees of Freedom of Optically Trapped Chromium Atoms Using Gray Molasses
L. Gabardos, S. Lepoutre, O. Gorceix +2
We report on a scheme to cool and compress trapped clouds of highly magnetic 52Cr atoms. This scheme combines sequences of gray molasses, which freeze the velocity distribution, an…
Collective spin modes of a trapped quantum ferrofluid
S. Lepoutre, L. Gabardos, K. Kechadi +5
We report on the observation of a collective spin mode in a spinor Bose-Einstein condensate. Initially, all spins point perpendicular to the external magnetic field. The lowest ene…
Note on the reflectance of mirrors exposed to a strontium beam
J. Huckans, W. Dubosclard, E. Maréchal +3
The high chemical reactivity of strontium, which can opacify a viewport exposed to a strontium atomic source, is a concern for some atomic physics experiments where it is sometimes…
Competition between Bose Einstein Condensation and spin dynamics
Bruno Naylor, Miroslaw Brewczyk, Mariusz Gajda +4
We study the impact of spin-exchange collisions on the dynamics of Bose-Einstein condensation, by rapidly cooling a chromium multi-component Bose gas. Despite relatively strong spi…
