Inhomogeneous Inflation as a probe of the shape of the potential

Presented by Josu C. AURREKOETXEA on 1 Jul 2019 from 15:30 to 15:50
Type: oral presentation
Track: Cosmological Probes


In this talk I will discuss how different inflationary models are sensitive to inhomogeneities in the initial scalar field profile. In particular I will demonstrate that convex potentials always support large inhomogeneities and are more robust than concave ones. We developed a prescription to predict when a concave inflationary potential fails and I will show how it can be used to infer the initial conditions needed for a given model to be safe.
