    "abstract": "We propose schemes for the unconditional preparation of a two-mode squeezed\nstate of effective bosonic modes realized in a pair of atomic ensembles\ninteracting collectively with optical cavity and laser fields. The scheme uses\nRaman transitions between stable atomic ground states and under ideal\nconditions produces pure entangled states in the steady state. The scheme works\nboth for ensembles confined within a single cavity and for ensembles confined\nin separate, cascaded cavities.",
