Long-range gravitational-like interaction in a neutral atomic cold gas
Résumé
A quasi resonant laser induces a long-range attractive force within a cloud of cold atoms. We take advantage of this force to build in the lab a systems of particles with a 1D gravitational-like interaction, at a fluid level of modeling. We give experimental evidences of such an interaction in a Strontium cold gas, studying the density profile of the cloud, its size as a function of the number of atoms and its breathing oscillations.
