我们计算了单场膨胀中由非bunch - davies初始状态引起的非高斯性的大尺度结构可观测值。这些场景可以从压缩(但可观察到的)动量构型中获得大量的原始非高斯性。他们在光环偏差中产生了一个术语,这个术语可能比来自当地ansatz的贡献更强烈地依赖于规模。我们还讨论了生成可观察签名所需的理论考虑。
We calculate Large Scale Structure observables for non-Gaussianity arising from non-Bunch-Davies initial states in single field inflation. These scenarios can have substantial primordial non-Gaussianity from squeezed (but observable) momentum configurations. They generate a term in the halo bias that may be more strongly scale-dependent than the contribution from the local ansatz. We also discuss theoretical considerations required to generate an observable signature.
