Abstract:

In this paper we propose a new and simple velocity selective method, which combines the velocity selective coherent population trapping of atoms in a light field and the kinetic energy coupling between the dark state and coupled state(s) during free flight, in order to reach a very narrow momentum distribution in a short period of time. This technique combined with force-assisted velocity selective coherent population trapping can produce very efficient cooling and trapping. It can also be used to overcome the cooling limit caused by the leakage of the dark state.

Abstract:

Proposed is an efficient quantum jump method that is suitable for the study of subrecoil cooling. The method is an improvement over using the numerical integration of Schrodinger equation to find delay time in which the excited state decay term is incorporated into the Hamiltonian making it a non-Hermitian matrix. 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.
