The results show : ( 1 ) that the dynamical properties in the system depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field , and the atomic dipole moment can be completely squeezed via choosing optimal degree of entanglement of the initial atoms in the feeblish optical field ; ( 2 ) that the quantum properties of the system also depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field , and the radiation field can be effectively squeezed via choosing optimal degree of entanglement of the initial atoms in the fee blish optical field ( 2 )相干态光场的强度和两原子的初始纠缠度对光场的量子特性也有很大的影响。光场的二阶相干性质(聚束与反聚束)和光场的压缩效应均与光场强度和两原子纠缠度相关联。在弱光场中,选择合适的两原子初始纠缠度,光场压缩深度和时间可达到最大。
