Spin mixing and protection of ferromagnetism in a spinor dipolar condensate
We study spin mixing dynamics in a chromium dipolar Bose-Einstein condensate, after tilting the atomic spins by an angle 𝜃 with respect to the magnetic field.

Competition between Bose-Einstein condensation and spin dynamics
We study the impact of spin-exchange collisions on the dynamics of Bose-Einstein condensation by rapidly cooling a chromium multicomponent Bose gas.

Large spin magnetism
Probing spin dynamics from the Mott insulating to the superfluid regime in a dipolar lattice gas
We analyze the spin dynamics of an out-of-equilibrium large spin dipolar atomic Bose gas in an optical lattice. We observe a smooth crossover from a complex oscillatory behavior to an exponential behavior throughout the Mott-to-superfluid transition.
