Quantum jump calculations of subrecoil cooling in one and two dimensions

Summary form only given. Fully quantum calculations are needed for laser cooling techniques in which the momentum of the atoms is reduced close to, or below, the recoil limit. We have proposed an efficient quantum jump method that is suitable for the study of subrecoil cooling. It can also be applied to the calculation of three-dimensional velocity selective coherent population trapping proposed by Mauri and Arimondo in F=3/2 to F=3/2 transition.
