We analyze a narrow Feshbach resonance with ultracold chromium atoms colliding in 𝑑 wave. The resonance is made possible by dipole-dipole interactions, which couple an incoming 𝑙=2 collision channel with a bound molecular state with 𝑙=0.

We study the effect of strong radio-frequency (RF) fields on a Bose-Einstein condensate (BEC) of chromium atoms, in a regime where the RF frequency is much larger than the Larmor frequency.

We report on the production of 52Cr Bose-Einstein condensates with an all-optical method.
arXiv:0712.3521 (2007) / Phys. Rev. A 77, 061601(R) (2008)
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.

We introduce a time-averaged trap in which the internal state of the atoms is rapidly modulated to modify the magnetic trapping potential.

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.

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.

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.

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.
