We find that the atomic dipole moment is dependent on the degree of squeezing. 我们发现原子偶极矩随时间的变化与压缩真空态光场的压缩参数|M|有关。
The expectation value of atom dipole moment is always zero, but the fluctuation of dipole moment is a constant and not zero during the atomic spontaneous emission. Therefore the spontaneous emission of atoms is caused by the fluctuation of dipole moment that arises from vacuum fluctuation. 在原子的自发辐射过程中,其偶极矩的期待值总是零,但偶极矩的涨落恒等于一个不为零的常量,因此原子的自发辐射是由真空起伏导致偶极矩的涨落引起的。
Below the threshold, the atomic dipole moment oscillates with resonance frequency only. 阈值之下,原子偶极矩以共振频率振荡;
