De Sitter holography and the cosmic microwave background

Research output: Contribution to journalArticlepeer-review


We interpret cosmological evolution holographically as a renormalisation group flow in a dual euclidean field theory, as suggested by the conjectured dS/CFT correspondence. Inflation is described by perturbing around the infra-red fixed point of the dual field theory. The spectrum of the cosmic microwave background radiation is determined in terms of scaling violations in the field theory. The dark energy allows similar, albeit less predictive, considerations. We discuss the cosmological fine-tuning problems from the holographic perspective.
