Atom and photon measurement in cooperative scattering by cold atoms / T. Bienaimé, M. Petruzzo, D. Bigerni, N. Piovella, R. Kaiser. - In: JOURNAL OF MODERN OPTICS. - ISSN 0950-0340. - 58:21(2011), pp. 1942-1950. [10.1080/09500340.2011.594911]
Abstract:
In this paper, we study cooperative scattering of low intensity light by a cloud of N two-level systems. We include
the incident laser field driving these two-level systems and compute the radiation pressure force on the center of mass of the cloud. This signature is of particular interest for experiments with laser cooled atoms. Including the
complex coupling between dipoles in a scalar model for dilute clouds of two-level systems, we obtain expression
for cooperative scattering forces taking into account the collective Lamb shift. We also derive the expression of
the radiation pressure force on a large cloud of two-level systems from an heuristic approach and show that at
lowest driving intensities this force is identical for a product and an entangled state.
