In a magneto-otpical trap (MOT) where atoms can be cooled and trapped using quasi-resonant laser light, the effect of rescattered light limits the spatial density of the atoms. Here we draw an analogy between the forces associated to this multiple scattering and a Coulomb type long range interaction. A MOT in the density limited regime can thus be interpreted as a non neutral plasma with weakly charged particles. For very large samples, non linear terms in the cooling and trapping forces can lead to self sustained instabilities via a supercritical Hopf bifurcation.
