Orbital Inflation: inflating along an angular isometry of field space
Ana Achucarro, Yvette Welling
The simplicity of the CMB data, so well described by single-field inflation, raises the question whether there might be an equally simple multi-field realization consistent with th…

On the viability of m**2 phi**2 and natural inflation
Ana Achucarro, Vicente Atal, Yvette Welling
In the context of single field inflation, models with a quadratic potential and models with a natural potential with subplanckian decay constant are in tension with the Planck data…

Multiple Field Inflation and Signatures of Heavy Physics in the CMB
Ana Achúcarro, Yvette Welling
In this master thesis we study multi-field inflation and the UV sensitivity of certain models of inflation in supergravity. We first introduce inflation and its current observation…
