Pattern of perturbations from a coherent quantum inflationary horizon

It is proposed that if quantum states of space-time are coherent on null surfaces, holographic Planck-scale fluctuations of inflationary horizons dominate the formation of primordial scalar curvature perturbations. It is shown that the reduction of quantum states on nearly-spherical emergent horizon surfaces around each observer creates a distinctive pattern whose correlations in the angular domain differ from the standard quantum theory of inflation. Causal constraints are used in a semiclassical model to formulate candidate directional symmetries. It is suggested that this hypothesis could provide a physical explanation for several well known anomalies measured in CMB anisotropy. New exact symmetries are predicted, such as a vanishing temperature correlation function at 90 degrees angular separation, that can be tested with current data.

来自相干量子暴胀视界的扰动模式

有人提出,如果时空的量子态在零表面上是相干的,那么暴胀视界的全息普朗克尺度波动将主导原始标量曲率扰动的形成。结果表明,每个观察者周围近乎球形的涌现视界表面上量子态的减少创造了一种独特的模式,其角域中的相关性不同于标准的量子暴涨理论。因果约束在半经典模型中用于制定候选方向对称性。有人认为,这一假设可以为在 CMB 各向异性中测量的几个众所周知的异常提供物理解释。预测了新的精确对称性,例如在 90 度角分离时消失的温度相关函数,可以使用当前数据进行测试。
