    "abstract": "Spin squeezing via atom-field interactions is considered within the context\nof the Tavis-Cummings model. An ensemble of N two-level atoms interacts with a\nquantized cavity field. For all the atoms initially in their ground states, it\nis shown that spin squeezing of both the atoms and the field can be achieved\nprovided the initial state of the cavity field has coherence between number\nstates differing by 2. Most of the discussion is restricted to the case of a\ncavity field initially in a coherent state, but initial squeezed states for the\nfield are also discussed. Optimal conditions for obtaining squeezing are\nobtained. An analytic solution is found that is valid in the limit that the\nnumber of atoms is much greater than unity and is also much larger than the\naverage number of photons, inititally in the coherent state of the cavity\nfield. In this limit, the degree of spin squeezing increases with increasing a,\neven though the field more closely resembles a classical field for which no\nspin squeezing could be achieved.",
