Resumen:
We consider the problem of an atomic three-level system in interaction with a radiation field. The time evolution of the system, in atomic ladder and ¤ con¯gurations, is solved exactly assuming a coherent-state as the initial atomic state. We calculate the atomic spin-squeezing, the atomic entropy-squeezing, and their variances. We show that the spin-squeezing and the entropy-squeezing exhibit similar time dependence.
