Robust non-minimal attractors in many-field inflation
Perseas Christodoulidis, Robert Rosati, Evangelos I. Sfakianakis
Multi-field inflation can be inherently non-predictive, with the exception of models with strong attractors. In this work, we focus on models with multiple scalar fields that are n…
Many-field Inflation: Universality or Prior Dependence?
Perseas Christodoulidis, Diederik Roest, Robert Rosati
We investigate the observational signatures of many-field inflation and present analytic expressions for the spectral index as a function of the prior. For a given prior we employ…
General solutions to -field cosmology with exponential potentials
Perseas Christodoulidis
We construct the general analytical solution for the -field product-exponential potential in an expanding FLRW background. We demonstrate the relevance of this analyti…
