Quantum thermalization of long-range interacting spins
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.

We introduce a spin-orbit coupling scheme, where a retroreflected laser beam selectively diffracts two spin components in opposite directions.

First experimental results using the degenerate Fermi gas! We used spin-orbit coupling to selectively manipulate and probe up to four selected spin states at once. We also present our new quantum gas machine setup, down to T/Tf ~ 0.2. Check it out here!
Detecting entanglement in large ensembles of large spin atoms
Shelving spectroscopy of the Sr intercombination line; Adiabatic spin-dependent momentum transfer in a degenerate Sr gas
We propose to realize a novel quantum simulator made of magnetic atoms in periodic potentials, which will enable the investigation of quantum-many body problems associated with long-range dipole-dipole interactions.
