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.
