Non-Gaussianity from Axion-Gauge Fields Interactions during Inflation
Emanuela Dimastrogiovanni, Matteo Fasiello, Robert J. Hardwick +3
We study the scalar-tensor-tensor non-Gaussian signal in an inflationary model comprising also an axion coupled with SU(2) gauge fields. In this set-up, metric fluctuations are sou…
The decisive future of inflation
Robert J. Hardwick, Vincent Vennin, David Wands
How much more will we learn about single-field inflationary models in the future? We address this question in the context of Bayesian design and information theory. We develop a no…
Multiple spectator condensates from inflation
Robert J. Hardwick
We investigate the development of spectator (light test) field condensates due to their quantum fluctuations in a de Sitter inflationary background, making use of the stochastic fo…
