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…
Radio-frequency induced ground state degeneracy in a Chromium Bose-Einstein condensate
Q. Beaufils, T. Zanon, R. Chicireanu +5
We study the effect of strong radio-frequency (rf) fields on a chromium Bose-Einstein condensate (BEC), in a regime where the rf frequency is much larger than the Larmor frequency.…
All-Optical Production of Chromium Bose-Einstein Condensates
Q. Beaufils, R. Chicireanu, T. Zanon +5
We report on the production of ^52Cr Bose Einstein Condensates (BEC) with an all-optical method. We first load 5.10^6 metastable chromium atoms in a 1D far-off-resonance optical tr…
Averaging out magnetic forces with fast rf-sweeps in an optical trap for metastable chromium atoms
Q. Beaufils, R. Chicireanu, A. Pouderous +6
We introduce a novel type of time-averaged trap, in which the internal state of the atoms is rapidly modulated to modify magnetic trapping potentials. In our experiment, fast radio…
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…
