Collective effects in the radiation pressure force / R. Bachelard, N. Piovella, W. Guerin, R. Kaiser. - In: PHYSICAL REVIEW A. - ISSN 2469-9926. - 94:3(2016 Sep 20). [10.1103/PhysRevA.94.033836]
Abstract:
We discuss the role of diffuse, Mie, and cooperative scattering on the radiation pressure force acting on the
center of mass of a cloud of cold atoms. Even though a mean-field ansatz (the “timed Dicke state”), previously
derived from a cooperative scattering approach, has been shown to agree satisfactorily with experiments, diffuse
scattering also describes very well most features of the radiation pressure force on large atomic clouds. We
compare in detail an incoherent, random walk model for photons and a diffraction approach to the more complete
description based on coherently coupled dipoles. We show that a cooperative scattering approach, although
it provides a quite complete description of the scattering process, is not necessary to explain the previous
experiments on the radiation pressure force.
