Pattern of perturbations from a coherent quantum inflationary horizon

Understand

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.
