Method to discriminate between localized and chaotic quantum systems
We study whether a generic isolated quantum system initially set out of equilibrium can be considered as localized close to its initial state. Our approach considers the time evolution in the Krylov basis, which maps the dynamics onto that of a particle moving in a one-dimensional lattice where both the energy in the lattice sites and the tunneling from one lattice site to the next are inhomogeneous.

Cavity is ready for vacuum
Atoms have been seen in the main chamber, within the internship work of Arthur Ilman. The optical cavity of the superradiant laser is ready to be installed in vacuum.

Correlations and linewidth of the atomic beam continuous superradiant laser
We propose a minimalistic model to account for the main properties of a continuous superradiant laser, in which a beam of atoms crosses the mode of a high-finesse Fabry-Perot cavity, and collectively emits light into the cavity mode.

Measuring correlations from the collective spin fluctuations of a large ensemble of lattice-trapped dipolar spin-3 atoms
We perform collective spin measurements to study the buildup of two-body correlations between ≈10^4 spin s=3 chromium atoms pinned in a 3D optical lattice.

Vacuum chamber assembly
The superradiant laser optical cavity spacer has been made and polished by the laboratory optician Thierry Billeton. Furthermore, the vacuum system is now assembled, but for the cavity.
