DYNAMICAL PROPERTIES OF ATOMS AND FIELD IN THE INTERACTION OF PAIR COHERENT STATE WITH TWO ATOMS
Tinglu Song
We study the dynamical poperties of atoms and field under the interaction of pair coherent state with two two-level atoms, and discuss how they are modified by dipole-dipole interaction. The numerical results show that the degrees and the revivals of the squeezing as well as the sum-squeezing of the field decrease with increasing dipole-dipole interaction. When the difference in the number of photons q increases, the degrees and the revivals of the squeezing as well as the sum-squeezing of the field decrease, the nonclassical correlation between two modes get weaker, the sub-Poissonian distribution for mode 1 get wider, and that for mode 2 becomes narrower in the collapse region. The increase in q results in speeding up of the energy exchange between atoms and the two-mode light field.
