Quantum magnetism with a dipolar BEC
Quantum magnetism with a dipolar BEC
We study dipolar relaxation of a chromium Bose-Einstein condensate loaded into a three-dimensional (3D) optical lattice.

Thermodynamics of spin 3 ultra-cold atoms with free magnetization
We measure the excitation spectrum of a dipolar chromium Bose-Einstein condensate with Raman-Bragg spectroscopy.

Spontaneous demagnetization of ultra cold chromium atoms at low magnetic fields
We study thermodynamic properties of a gas of spin 3 52Cr atoms across Bose-Einstein condensation. Magnetization is free, due to dipole-dipole interactions.

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