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 đ =3 chromium atoms, under the effect of dipolar interactions.

Adiabatic spin-dependent momentum transfer in an SU(đ) degenerate Fermi gas
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
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!

Shelving spectroscopy of the Sr intercombination line; Adiabatic spin-dependent momentum transfer in a degenerate Sr gas
Magnetic Atoms Quantum Simulators / QUANTERA CONSORTIUM MAQS
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.
Shelving spectroscopy of the strontium intercombination line
We present a spectroscopy scheme for the 7 kHz wide 689 nm intercombination line of strontium. We rely on shelving detection, where electrons are first excited to a metastable state by the spectroscopy laser before their state is probed using the broad transition at 461 nm.

New spectroscopy scheme
We concluded a great collaborative work with Marc Cheneau and his team, at Laboratoire Charles Fabry, on a new spectroscopy scheme for the intercombination line for strontium. For a large spectroscopy signal and a low complexity, look here.
Excitation spectrum and supersolidity of a two-leg bosonic ring ladder
We consider a system of weakly interacting bosons confined on a planar double lattice ring subjected to two artificial gauge fields… Our analysis reveals supersolid features as well as Josephson modes, corresponding to out-of-phase modes of the finite ring.
