Measuring densities of cold atomic clouds smaller than the resolution limit
We propose and demonstrate an experimental method to measure by absorption imaging the size and local column density of a cloud of atoms, even when its smallest dimension is smaller than the resolution of the imaging system.

Quantum thermalization of long-range interacting spins
Relaxation of the collective magnetization of a dense 3D array of interacting dipolar S = 3 atoms
We report on measurements of the dynamics of the total magnetization and spin populations in an almost unit-filled lattice system comprising about 10^4 spin 𝑆 =3 chromium atoms, under the effect of dipolar interactions.

Adiabatic spin-dependent momentum transfer in an SU(𝑁) degenerate Fermi gas
We introduce a spin-orbit coupling scheme, where a retroreflected laser beam selectively diffracts two spin components in opposite directions.
