| 摘 要： | 通过严格解主方程求出原子-腔场复合系统密度算符矩阵元,研究了初始处于真空耗散腔中二能级原子偶极压缩和腔场压缩特性。结果表明,在共振相互作用下腔耗对原子和场的压缩都有显著影响,但在非共振相互作用条件下腔耗对原子和场的压缩影响下降.

| Abstract: | The field squeezing and the atomic dipole squeezing of a two-level atom in a dissipative cavity initially in vacuum are investigated.By means of exact solution of the master equation,the matrix elements of the density operator of the compound atom-field system are obtained.It is found that the cavity dissipation has an obvious influence on the atomic squeezing and the field squeezing under the resonant atom-field interaction.But the effects of the cavity dissipation on both squeezing will decrease under the off-resonance interaction condition. |
