Palatini inflationary (non-)attractors: Universal mapping of observables
Christian Dioguardi, Francesco Gianesello, Antonio Racioppi
We study single-field slow-roll inflation in the context of Palatini gravity for the class of non-minimally coupled -attractors, i.e.,\ models where the same function fix…
Inflation with Nieh-Yan-like terms in metric-affine gravity
Ilaria Andrei, Christian Dioguardi, Damianos Iosifidis +3
We study single-field slow-roll inflation in metric-affine gravity with a scalar field non-minimally coupled to the non-Riemannian Ricci scalar and to the divergences of the torsio…
Quasi-pole quintessential inflation in metric-affine gravity
Konstantinos Dimopoulos, Christian Dioguardi, Ioannis D. Gialamas +1
We study quintessential inflation in the framework of metric-affine gravity. It is well known that non-minimal couplings with the Holst invariant can generate a quasi-pole inflatio…
Quasi-pole inflation in metric-affine gravity
Antonio Racioppi
We propose a new mechanism for inflationary model building in the framework of metric-affine gravity. Such a mechanism involves an inflaton non-minimally coupled with the Holst inv…
Natural inflation in Palatini
N. Bostan, R. H. Dejrah, C. Dioguardi +1
Palatini gravity provides a robust framework for constructing viable inflationary potentials. In this study, we examine natural inflation and show that its consistency with…
Has ACT measured radiative corrections to the tree-level Higgs-like inflation?
Ioannis D. Gialamas, Alexandros Karam, Antonio Racioppi +1
Starobinsky inflation and nonminimally coupled (NMC) Higgs inflation have been among the most favored models of the early Universe, as their predictions for the scalar spectral ind…
