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…
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…
Dipolar atomic spin ensembles in a double-well potential
A. de Paz, B. Naylor, J. Huckans A. Carrance +5
We experimentally study the spin dynamics of mesoscopic ensembles of ultracold magnetic spin-3 atoms located in two separated wells of an optical dipole trap. We use a radio-freque…
Radio-frequency association of molecules: the dressed state picture
Q. Beaufils, A. Crubellier, T. Zanon +4
We develop a theoretical model to describe the radio-frequency (rf) induced coupling of a pair of colliding atoms to a Feshbach molecule when a magnetic field arbitrarily far from…
A Feshbach resonance in d-wave collisions
Q. Beaufils, A. Crubellier, T. Zanon +4
We analyse a narrow Feshbach resonance with ultra-cold chromium atoms colliding in d-wave. The resonance is made possible by dipole-dipole interactions, which couple an incoming $l…
A magnetic lens for cold atoms controlled by a rf field
E. Marechal, B. Laburthe-Tolra, L. Vernac +2
We report on a new type of magnetic lens that focuses atomic clouds using a static inhomogeneous magnetic field in combination with a radio-frequency field. The experimental study…
