    "abstract": "We present a Gaussian state analysis of the entanglement generation between\ntwo macroscopic atomic ensembles due the continuous probing of collective spin\nvariables by optical Faraday rotation. The evolution of the mean values and the\nvariances of the atomic variables is determined and the entanglement is\ncharacterized by the Gaussian entanglement of formation (GEoF) and the\nlogarithmic negativity. The effects of induced opposite Larmor rotation of the\nsamples and of light absorption and atomic decay are analyzed in detail.",
