    "abstract": "The Gaussian state description of continuous variables is adapted to describe\nthe quantum interaction between macroscopic atomic samples and continuous-wave\nlight beams. The formalism is very efficient: a non-linear differential\nequation for the covariance matrix of the atomic system explicitly accounts for\nboth the unitary evolution, the dissipation and noise due to the atom-light\ninteraction, and the back-action due to homodyne optical detection on the beam\nafter its interaction with the atoms. Applications to atomic spin squeezing and\nestimation of unknown classical parameters are presented, and extensions beyond\nthe Gaussian states are discussed.",
