多极Jaynes-Cummings模型中辐射的极化

Polarization of Radiation in Multipole Jaynes-Cummings Model

Muhammet Ali Can, Alexander S. Shumovsky

摘要:

讨论了单原子多极跃迁辐射的空间性质。研究了光子平面波和球面波的表示之间的质的差别。特别地,多极场零点振荡的空间不均匀性被示出。我们表明,真空噪声的偏振集中在一定的原子附近,它强烈超过了平面波的表示所预测的水平。提出了一种新的广义极化矩阵。结果表明,极化及其真空噪声强烈依赖于距源的距离。

英文摘要:

We discuss the spatial properties of quantum radiation emitted by a multipole transition in a single atom. The qualitative difference between the representations of plane and spherical waves of photons is examined. In particular, the spatial inhomogeneity of the zero-point oscillations of multipole field is shown. We show that the vacuum noise of polarization is concentrated in a certain vicinity of atoms where it strongly exceeds the level predicted by the representation of the plane waves. A new general polarization matrix is proposed. It is shown that the polarization and its vacuum noise strongly depend on the distance from the source.
