我们证明，广义相对论与量子场论的结合通常会导致物质领域的非局域效应。这些非局部效应可以通过非局部高维算子来描述，这些算子非常具有近似的移位对称性。当应用于暴胀模型时，我们的结果意味着小的非高斯性是基于广义相对论与物质场耦合的模型的一般特征。然而，这些效应太小，无法在宇宙微波背景下观察到。
We show that general relativity coupled to a quantum field theory generically leads to non-local effects in the matter sector. These non-local effects can be described by non-local higher dimensional operators which remarkably have an approximate shift symmetry. When applied to inflationary models, our results imply that small non-Gaussianities are a generic feature of models based on general relativity coupled to matter fields. However, these effects are too small to be observable in the cosmic microwave background.
