An Hamilton-Jacobi formulation of anisotropic inflation
Francesco Cicciarella, Joel Mabillard, Mauro Pieroni +1
Classifying inflationary scenarios according to their scaling properties is a powerful way to connect theory with observations. A useful tool to make such a classification is the b…
Identifying Universality in Warm Inflation
Arjun Berera, Joel Mabillard, Mauro Pieroni +1
Ideas borrowed from renormalization group are applied to warm inflation to characterize the inflationary epoch in terms of flows away from the de Sitter regime. In this framework d…
New perspectives on constant-roll inflation
F. Cicciarella, J. Mabillard, M. Pieroni
We study constant-roll inflation using the -function formalism. We show that the constant rate of the inflaton roll is translated into a first order differential equation for th…
Universality classes for models of inflation
P. Binetruy, E. Kiritsis, J. Mabillard +2
We show that the cosmological evolution of a scalar field in a potential can be obtained from a renormalisation group equation. The slow roll regime of inflation models is understo…
