摘　　要：考虑将3个全同的二能级原子分别囚禁在3个耦合腔中,并且腔场处于弱相干态的情况。利用数值计算方法研究了原子的偶极压缩效应,讨论了腔场间的耦合系数和腔场的强度对原子偶极压缩的影响。研究结果表明:随腔场间耦合增强,压缩效应减弱。另一方面,随弱相干光场强度的加强,原子的偶极压缩效应增强。We study atomic dipole squeezing of the system comprising three two-level atoms resonantly interacting with three coupled cavities which are in weak coherent states initially. The atomic dipole squeezing is investigated. The influences of coupling constant between cavities and intensity of the cavity field on atomic dipole squeezing are discussed. The results obtained using the numerical method show that atomic dipole squeezing is weakened with the increase of the coupling constant between the cavities. On the other hand, atomic dipole squeezing is strengthened with increase of intensity of the cavity field.
