We measure the excitation spectrum of a dipolar chromium Bose-Einstein condensate with Raman-Bragg spectroscopy.

We study thermodynamic properties of a gas of spin 3 52Cr atoms across Bose-Einstein condensation. Magnetization is free, due to dipole-dipole interactions.

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

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.

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.

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).

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.

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.
