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.…
Doppler-free spectroscopy of the 1S0-3P0 optical clock transition in laser-cooled fermionic isotopes of neutral mercury
M. Petersen, R. Chicireanu, S. T. Dawkins +5
We have performed for the first time direct laser spectroscopy of the 1S0-3P0 optical clock transition at 265.6 nm in fermionic isotopes of neutral mercury laser-cooled in a magnet…
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…
Accumulation and thermalization of cold atoms in a finite-depth magnetic trap
R. Chicireanu, Q. Beaufils, A. Pouderous +6
We experimentally and theoretically study the continuous accumulation of cold atoms from a magneto-optical trap (MOT) into a finite depth trap, consisting in a magnetic quadrupole…
