Long range forces

Triggered by the experimental observation of self-sustained oscillations in a magneto-optical trap (see the 2006 Phys. Rev. Lett. below), we started to investigate theoretically the light-induced long-range forces between cold atoms, in particular the interesting analogies with plasma physics and gravitational systems. We also studied experimentaly the consequences of these forces on the behavior of large magneto-optical traps, in particular their scaling laws (e.g. size vs atom number).
