论文摘要
我们考虑将带电的充气量加热,该充气量最小化与电磁作用。这种反弹的演变诱导光子的时间依赖性质量。我们展示了如何将巨大的光子传播器表示为空间傅立叶模式和涉及三种不同的模式函数,就像恒定的质量情况一样。我们为这些模式函数开发了准确的分析近似值,并使用它们来近似于加拉顿$ 0 $ -MODE上的有效力。这种有效的力量使人们可以简单地计算Adflaton $ 0 $ mode的演变,并遵循再加热的进度。
We consider reheating for a charged inflaton which is minimally coupled to electromagnetism. The evolution of such an inflaton induces a time-dependent mass for the photon. We show how the massive photon propagator can be expressed as a spatial Fourier mode sum involving three different sorts of mode functions, just like the constant mass case. We develop accurate analytic approximations for these mode functions, and use them to approximate the effective force exerted on the inflaton $0$-mode. This effective force allows one to simply compute the evolution of the inflaton $0$-mode and to follow the progress of reheating.
