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…
Accumulation of chromium metastable atoms into an Optical Trap
R. Chicireanu, Q. Beaufils, A. Pouderous +5
We report the fast accumulation of a large number of metastable 52Cr atoms in a mixed trap, formed by the superposition of a strongly confining optical trap and a quadrupolar magne…
