We study the squeezing and the amplitude-squared squeezing of radiation field in the interaction of squeezed vacuum state with two two-level atoms, and discuss the effects of the relative value of two atom-field coupling constants on them. The numerical results show that the presence of one additional atom introduces nontrivival cooperative effects into the squeezing and the amplitude-squared squeezing of radiation field.

In this article,by means of solving Schrdinger equation and numerical calculations,the radiation squeezing effects in the system of the binomial states field interacting with a moving two-level atom has been discussed.The results indicate that the radiation field can show complete squeezing effects when the system parameters are selected appropriately.

The radiation squeezing effect in the interaction process between the single mode squeezed vacuum field and a moving two-level atom is studied by means of solving the Schrdinger equation and numerical calculations.The results are as follows: with the increasing of the atom's speed and the parameter of field model structure,the time evolution curve rises noticeably;with the rising of the probability breadth of the atom ground state,the squeezing depth of the radiation field increases,otherwise it decreases,even there is no squeeze;the phase angle effects the time evolution curve's change like the probability breadth of the atom ground state;during the process that the compression factor becomes larger,the radiation field can not squeeze firstly,then it squeezes partially,finally the squeeze gradually disappears.
