atomic dipole moment
atomic dipple moment
Examples
- In chapter 2 , the dynamics behaviors of quantum information entropy squeezing of the atomic dipoles are investigated without considering the dissipation from the environment
第二章研究不考虑环境影响下原子偶极矩信息熵压缩的动力学。 - Therefore it is considered that the spontaneous emission of atom is caused by the fluctuation of dipole moment , not by the dipole moment oscillation of the atomic system
原子偶极矩的期待值总是零，但偶极矩的起伏恒等于一个不为零的常数，因此，原子的自发辐射是由偶极矩的涨落引起的，并非原子偶极矩振荡造成的结果。 - The results show that the number of the squeezed atomic dipoles is decided by the coherence of the atom , the direction of the quantum information entropy squeezing is decided by the phases of the field and the atom , and the quantum information entropy squeezing is a precision tool for the squeezing of the atom , especially when the atom is in the eigenstates of the dipole operators
结果表明：原子偶极矩分量出现信息熵压缩的数目依赖于原子的分布角；信息熵压缩的方向由原子和场的位相决定；量子信息熵是原子压缩的精密量度工具，尤其适合于原子处在偶极矩算符的本征态时压缩情况的描述。 - Finally we focus our attention on studying the emission spectrum of two atoms driven by a single - mode field in an ideal cavity . we showed that the atomic emission spectrum is insensitive to the phase of field for the two atoms initially in the coherent superposition state tf / = v2 / 2 ( j + , - ) h ? + } ) , when the two atoms is initially prepared in ( fs * } = cos ( 0 / 2 ] + , + ) + sm ( 0 / 2 ) ei ' p - , - ) , the atomic emission spectrum is associated with not only the field photon - number distribution and the atomic populations , but also the phases of the field and the atomic dipole
接着考察了好腔中由单模量子场驱动的双原子发射谱，结果表明初态为的双原子发射谱与驱动场的相位无关；而初态为的双原子发射谱不仅与光场的光子数分布以及原子的布居数有关，而且依赖于光场的相位以及原子偶极矩的相位，并且在适当的条件下，压缩真空场可将双原子俘获在相干叠加态。 - When the cavity field is initially in photon number state or mixed state , the emission spectrum of the two - level atom has nothing to do with the phase of the atomic dipole . if the cavity field is initially in the coherent superposition of photon number state , the emission spectrum of the two - level atom exhibits phase sensitivity . if a a - type three - level atom is initially in the coherent superposition of its two non - degenerate lower states , the emission spectrum depends on the phase of the atomic dipole
证明了初始时刻驱动场处于光子数态或者光子数的混合态时，二能级原子发射谱与原子偶极矩的相位无关，只有当驱动场初始时刻处于光子数的叠加态时，原子发射谱才依赖于原子偶极矩的相位；而初始时刻处于两个下能态相干叠加态的型三能级原子发射谱对原子初态的依赖关系却不受单模驱动场的影响。
