论文摘要
量子场理论通常用于描述宇宙膨胀期间大规模重力扰动的起源，已被证明忽略了弯曲时空的重要物理作用，这是量化的物理效应，这是由于其对因果结构的重力效应而在量化模式中的非本地纠缠。在这里认为，在一个相干保留非局部定向和因果关系的量子重力模型中，原始扰动起源于出现的紧密量化膨胀范围的相干量子变形。此外，该因果约束解释了在大角度分离下测得的宇宙微波背景相关性的近似对称性，这在标准图片中是高度异常的。因此，在大角度CMB模式中已经明显的对称性可能是量子重力出现的局部性和因果结构的独特特征。
Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physical effect in curved space-time, the nonlocal entanglement among quantized modes from their gravitational effect on causal structure. It is argued here that in a different model of quantum gravity that coherently preserves nonlocal directional and causal relationships, primordial perturbations originate instead from coherent quantum distortions of emergent inflationary horizons; and moreover, that causal constraints account for approximate symmetries of cosmic microwave background correlations measured at large angular separations, which are highly anomalous in the standard picture. Thus, symmetries already apparent in the large-angle CMB pattern may be unique signatures of the emergence of locality and causal structure from quantum gravity.
