ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevA.88.033827 | Abstract: | Starting from a microscopic theory for atomic scatterers, we describe the scattering of light by a single atom and study the coherent propagation of light in a cold atomic cloud in the presence of a magnetic field B in the mesoscopic regime. Nonpertubative expressions in B are given for the magneto-optical effects and optical anisotropy. We then consider the multiple-scattering regime and address the fate of the coherent-backscattering (CBS) effect. We show that, for atoms with nonzero spin in their ground state, the CBS interference contrast can be increased compared to its value when B=0, a result at variance with classical samples. We validate our theoretical results by a quantitative comparison with experimental data. © 2013 American Physical Society. | Source Title: | Physical Review A - Atomic, Molecular, and Optical Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/115821 | ISSN: | 10502947 | DOI: | 10.1103/PhysRevA.88.033827 |
