Role of Mie scattering in the seeding of matter-wave superradiance / R. Bachelard, H. Bender, P.W. Courteille, N. Piovella, C. Stehle, C. Zimmermann, S. Slama. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 86:4(2012), pp. 043605.1-043605.4. [10.1103/PhysRevA.86.043605]
Abstract:
Matter-wave superradiance is based on the interplay between ultracold atoms coherently organized in momentum space and a backscattered wave. Here, we show that this mechanism may be triggered by Mie scattering from the atomic cloud.We show how the laser light populates the modes of the cloud and thus imprints
a phase gradient on the excited atomic dipoles. The interference with the atoms in the ground state results in a
grating that in turn generates coherent emission, contributing to the backward light wave onset. The atomic recoil
“halos” created by the Mie-scattered light exhibit a strong anisotropy, in contrast to single-atom scattering.
