论文摘要
我们为弯曲空间中真空中微子振荡提供了一种量子场理论方法，我们分析了量子场混合与弯曲空间中的量子场量化之间的非平凡相互作用，并得出了新的振荡公式。我们在空间平坦的FLRW指标中明确计算公式，以宇宙常数和辐射为主的宇宙。我们评估了Schwarzschild Black Hole指标中的过渡概率，我们表明鹰辐射会影响中微子的振荡。我们表明，当考虑量子机械限制时，我们的结果与先前分析的结果一致。
We present a quantum field theoretical approach to the vacuum neutrino oscillations in curved space, we analyze the non--trivial interplay between quantum field mixing and field quantization in curved space and derive new oscillation formulae. We compute the formulae explicitly in the spatially flat FLRW metrics for universes dominated by a cosmological constant and by radiation. We evaluate the transition probabilities in the Schwarzschild black hole metric, and we show that the Hawking radiation affects the oscillations of neutrinos. We show that our results are consistent with those of previous analyses when the quantum mechanical limit is considered.
