摘要

我们量化了真空中存在不运动的介电球时的电磁场。假定球体是无损的、无色散的、各向同性的和均匀的。量化是使用归一化特征模以及平面波模进行的。我们指定了两个有用的归一化本征模的备选基:球面本征模和散射本征模。推导了平面波模态与归一化本征模态之间的正则变换。用这种形式研究了单光子、相干压缩光和双光子态在介电球上的散射。在后一种情况下,我们计算了散射场的二阶相关函数,从而揭示了作为三维分束器的介电球的Hong-Ou-Mandel干涉的角分布。我们的结果是对任意折射率和大小的介电球的解析推导,特别强调了小颗粒的限制。如物理学所示。PLRAAN 1050-2947 10.1103/PhysRevA.108.033714,本工作为描述光与介电球的运动、旋转和振动自由度之间的量子相互作用奠定了理论基础。

Quantum Electrodynamics with a Nonmoving Dielectric Sphere: Quantizing Lorenz-Mie Scattering
We quantize the electromagnetic field in the presence of a nonmoving dielectric sphere in vacuum. The sphere is assumed to be lossless, dispersionless, isotropic, and homogeneous. The quantization is performed using normalized eigenmodes as well as plane-wave modes. We specify two useful alternative bases of normalized eigenmodes: spherical eigenmodes and scattering eigenmodes. A canonical transformation between plane-wave modes and normalized eigenmodes is derived. This formalism is employed to study the scattering of a single photon, coherent squeezed light, and two-photon states off a dielectric sphere. In the latter case, we calculate the second-order correlation function of the scattered field, thereby unveiling the angular distribution of the Hong–Ou–Mandel interference for a dielectric sphere acting as a three-dimensional beam splitter. Our results are analytically derived for a dielectric sphere of arbitrary refractive index and size with a particular emphasis on the small-particle limit. As shown in Phys. Rev. A 108 , 033714 ( 2023 ) PLRAAN 1050-2947 10.1103/PhysRevA.108.033714 , this work sets the theoretical foundation for describing the quantum interaction between light and the motional, rotational, and vibrational degrees of freedom of a dielectric sphere.
