Fig. 1.

Schematic picture of the subrecoil laser cooling process in momentum space. Photon scatterings induce a random walk for the momentum of the atoms, with steps of the order of , the photon momentum. The mean waiting time at momentum becomes very large for , thus generating an accumulation of atoms near .

Schematic view of the energy landscape in the trap model. A particle is trapped in deep energy wells or traps of energy ( is the depth of the trap) and can only escape by thermal activation. Once the particle leaves a trap, it chooses another trap at random among all the others.
