Evolution of non-Gaussianity in multi-scalar field models
Joseph Elliston, David Mulryne, David Seery +1
We study the evolution of non-Gaussianity in multiple-field inflationary models, focusing on three fundamental questions: (a) How is the sign and peak magnitude of the non-linearit…
Evolution of fNL to the adiabatic limit
Joseph Elliston, David J. Mulryne, David Seery +1
We study inflationary perturbations in multiple-field models, for which zeta typically evolves until all isocurvature modes decay--the "adiabatic limit". We use numerical methods t…
Chaotic inflation in modified gravitational theories
Antonio De Felice, Shinji Tsujikawa, Joseph Elliston +1
We study chaotic inflation in the context of modified gravitational theories. Our analysis covers models based on (i) a field coupling with the kinetic energy and a nonm…
