We study the spinor properties of 𝑆 =3 52Cr condensates, in which dipole-dipole interactions allow changes in magnetization.

Elastic and inelastic dipolar effects in chromium BECs
We observe interband transitions mediated by dipole-dipole interactions for an array of 1D quantum gases of chromium atoms, trapped in a 2D optical lattice.

Elastic and inelastic dipolar effects in chromium BECs
We have measured the effect of dipole-dipole interactions on the frequency of a collective mode of a Bose-Einstein condensate.

We report on a strategy to maximize the number of chromium atoms transferred from a magneto-optical trap into an optical trap through accumulation in metastable states via strong optical pumping.

Elastic and inelastic dipolar effects in chromium BECs
We study dipolar relaxation in both ultracold thermal and Bose-condensed Cr atom gases. We show three different ways to control dipolar relaxation, making use of either a static magnetic field, an oscillatory magnetic field, or an optical lattice to reduce the dimensionality of the gas from three-dimensional (3D) to two-dimensional (2D).
