Palatini-Higgs inflation with non-minimal derivative coupling
Ioannis D. Gialamas, Alexandros Karam, Angelos Lykkas +1
The predictions of standard Higgs inflation in the framework of the metric formalism yield a tensor-to-scalar ratio which lies well within the expected accuracy of…
Equivalence of inflationary models between the metric and Palatini formulation of scalar-tensor theories
Laur Järv, Alexandros Karam, Aleksander Kozak +3
With a scalar field non-minimally coupled to curvature, the underlying geometry and variational principle of gravity - metric or Palatini - becomes important and makes a difference…
Constant-roll in the Palatini- models
Ignatios Antoniadis, Angelos Lykkas, Kyriakos Tamvakis
We consider models of a scalar field coupled to quadratic gravity in the framework of the Palatini formulation. The resulting Einstein-frame generalized -inflation e…
