    "abstract": "We propose a scheme of generating and verifying mesoscopic-level entanglement\nbetween two atomic ensembles using non-resonant stimulated Raman scattering.\nEntanglement can be generated by direct detection or balanced homodyne\ndetection of the Stokes fields from the two cells, after they interfere on a\nbeam splitter. The entanglement of the collective atomic fields can be\ntransferred to the anti-Stokes fields in a readout process. By measuring the\noperator moments of the anti-Stokes fields, we can verify the presence of\nentanglement. We model the effects of practical factors such as Stokes field\ndetector quantum efficiency and additive thermal noise in the entanglement\ngenerating process, and anti-Stokes field losses in the entanglement\nverification process, and find achievable regimes in which entanglement can be\nverified at the levels of tens to hundreds of atomic excitations in the\nensembles.",
