Diagrammatic approach to coherent backscattering of laser light by cold atoms: Double scattering revisited [PDF]
J. Phys. B 45, 215501 (2012), 2012 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.

Analysis of the atom-number correlation function in a few-atom trap [PDF]
arXiv, 2006 Stochastic properties of loading and loss mechanism in a few atom trap are analyzed. An approximate formula is derived for the atom-number correlation function for the trapped atoms in the limit of reasonably small two-atom loss rate. Validity of the approximate formula is confirmed by numerical simulations.
