Diagrammatic approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
arXiv:1204.1512 · doi:10.1088/0953-4075/45/21/215501
Abstract
We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduced from single-atom responses, and provide a physical interpretation of the single-atom building blocks.
