论文摘要
光子的规范量化（一个游离无质量矢量场）在宇宙学的空间中被考虑在两参数的线性仪表家族中，这些量子量表将所有矢量电位分量在相等的基础上处理所有矢量电位分量。目的是设置一个计算光子两点函数的框架，适合于现实的通货膨胀空间中的循环计算。量化是在不依赖时空对称性的情况下实施的，而是基于经典的规范结构。特别关注规范的一流约束结构的量化，该结构被实施为物理状态的条件。这种情况会引起辅助条件，即光子两点函数必须满足。发现文献中的一些De Sitter空间光子传播器并不满足这些子公司条件，从而质疑它们的一致性。
Canonical quantization of the photon -- a free massless vector field -- is considered in cosmological spacetimes in a two-parameter family of linear gauges that treat all the vector potential components on equal footing. The goal is setting up a framework for computing photon two-point functions appropriate for loop computations in realistic inflationary spacetimes. The quantization is implemented without relying on spacetime symmetries, but rather it is based on the classical canonical structure. Special attention is paid to the quantization of the canonical first-class constraint structure that is implemented as the condition on the physical states. This condition gives rise to subsidiary conditions that the photon two-point functions must satisfy. Some of the de Sitter space photon propagators from the literature are found not to satisfy these subsidiary conditions, bringing into question their consistency.
