“Interplay between two, few- and manybody effects in a dense, cold and disordered gases
in strong dipole-dipole coupling”
Dipole-dipole long-range interactions between two atoms in dense and cold atomic media
play a crucial role in many configurations by considering ground state atoms as well as
highly-excited Rydberg atoms. They may alter the coherent scattering of light by a dense
and cold atomic sample. They open also many opportunities for studying few-body and
many-body physics, and hopefully for simulating many different quantum systems. A cold,
disordered and dense cesium Rydberg gas in Förster resonant configurations is an
interesting example of out-of-equilibrium quantum system. The atoms are prepared in a
state, np, exchanging internal energy by a resonant way
