Radio-frequency association of molecules: the dressed state picture
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 the Feshbach resonance is modulated in time.

A Feshbach resonance in d-wave collisions
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.

Bose-Einstein condensation in chromium and rf-assisted dipolar collisions
Radio-frequency-induced ground-state degeneracy in a Bose-Einstein condensate of chromium atoms
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.

Condensation de Bose-Einstein 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.
