摘要

We discuss the effects of the initial atomic coherent factors (including the phase and the distribution parameter)and the dipole-dipole interaction on the sum and two-atom dipole squeezing in the system. The results show thatthe maximum squeezing in both cases is determined by the phase and the distribution parameter, and the duration ofsqueezing becomes longer by strengthening the dipole-dipole interaction. In addition, the comparison of the two typesof squeezing shows that one type of squeezing is obtained at the expense of increased fluctuations in the other squeezingfunction.
