Abstract
We study the influence of atomic motion on the optical properties of atomic ensembles cooled in special laser traps. We analyze the possibility to simulate the continuous displacement of atoms within the framework of motionless coupled dipoles method, in which slow motion is modeled, firstly, by averaging over their random spatial distribution, and, secondly, by introducing a random shift of their frequencies, simulating Doppler effects. A direct comparison of the results obtained for moving atoms with the model ones revealed a very limited range of applicability of the latter.
