Ultracold collisions in chromium
Condensation du chrome et collisions assistées par des champs radiofréquences
One-dimensional (1D) dipolar quantum gases are characterized by a very special condition where super-strong correlations occur to significantly affect the static and dynamical low-energy behavior.

Condensation du chrome et collisions assistées par champs radio-fréquence
Dipolar relaxation in a chromium Bose-Einstein condensate
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.

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.
