Studies of inflation and dark energy with coupled scalar fields
Susan Vu
Currently there is no definitive description for the accelerated expansion of the Universe at both early and late times; we know these two periods as the epochs of inflation and da…
Effect of transitions in the Planck mass during inflation on primordial power spectra
Amjad Ashoorioon, Carsten van de Bruck, Peter Millington +1
We study the effect of sudden transitions in the effective Planck mass during inflation on primordial power spectra. Specifically, we consider models in which this variation result…
Constraints on Disformal Couplings from the Properties of the Cosmic Microwave Background Radiation
Carsten van de Bruck, Jack Morrice, Susan Vu
Certain modified gravity theories predict the existence of an additional, non-conformally coupled scalar field. A disformal coupling of the field to the Cosmic Microwave Background…
The Non-Adiabatic Pressure Perturbation and Non-Canonical Kinetic Terms in Multifield Inflation
C. van de Bruck, S. Vu
The evolution of the non-adiabatic pressure perturbation during inflation driven by two scalar fields is studied numerically for three different types of models. In the first model…
