Condensation du chrome
A magnetic lens for cold atoms controlled by a RF field
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 (RF) field.

Studies of cold chromium atoms in magnetic and optical traps: steps toward Bose-Einstein condensation
Averaging out magnetic forces with fast RF sweeps in an optical trap for metastable chromium atoms
We introduce a time-averaged trap in which the internal state of the atoms is rapidly modulated to modify the magnetic trapping potential.

Accumulation of chromium metastable atoms into an optical trap
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 magnetic trap.

Accumulation and thermalization of cold atoms in a finite-depth magnetic trap
We study the continuous accumulation of cold atoms from a magneto-optical trap (MOT) into a finite depth trap, consisting in a magnetic quadrupole trap dressed by a radiofrequency (RF) field.

Simultaneous magneto-optical trapping of bosonic and fermionic chromium atoms
We report on magneto-optical trapping of fermionic 53Cr atoms.

Optimized production of large Bose-Einstein condensates
We describe several routes to quantum degenerate gases based on simple schemes to efficiently load atoms into and evaporate them from a “dimple” crossed dipolar trap.

High flux source of cold rubidium atoms
We report the production of a continuous, slow, and cold beam of 87Rb atoms with an unprecedented flux of 3.2 x 10^12 atoms/s and a temperature of a few milliKelvin.
