摘要:

结果表明,电偶极光子的自旋和轨道角动量具有相同的算符结构,可能彼此不同,只是在原子附近的空间依赖性。结果表明,由偶极禁戒跃迁产生的光子孪晶可以表现出相对于角动量的最大纠缠。结果表明,具有角动量投影$m=0$的光子态比具有$m= \pm 1$的光子态稳定性差。

英文摘要:

It is shown that the spin and orbital angular momentum of electric dipole photons have the same operator structure and may differ from each other only by spatial dependence in the very vicinity of the atom. It is shown that the photon twins created by a dipole forbidden transition can manifest the maximum entanglement with respect to the angular momentum. It is shown that the states of photons with projection of angular momentum $m=0$ are less stable than those with $m= \pm 1$.
