Multi-field inflationary trajectories with a fast-turn feature

Turzynski, K (Uniwersytet Warszawski)
Tuesday 26 June 2012, 15:15-15:30

Seminar Room 2, Newton Institute Gatehouse


We study models of multi-field inflation in which the inflationary trajectory contains a strong bending occurring when the observable scales are still inside the Hubble radius. We discuss the impact of such a fast-tirn feature on the dynamics of the inflationary perturbations - and the traces such an event may leave in the power spectrum of curvature perturbations.
