Einstein-Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis
Carlo Di Benedetto, Alessandro Di Marco, Emanuele Orazi +1
We study the postinflationary dynamics of an Einstein-Cartan-Holst gravity-motivated inflationary scenario, known as Einstein-Cartan pseudoscalaron inflation, coupled to a type-I s…
Slowly rotating charged BTZ black hole solutions in Palatini Chern-Simons gravity
Flavio Bombacigno, Gonzalo J. Olmo, Emanuele Orazi +1
We consider a metric-affine formulation of Chern-Simons modified gravity in 2 + 1 dimensions. The theory is built requiring projective invariance, and the structure of the equation…
Introduction to the number of -folds in slow-roll inflation
Alessandro Di Marco, Emanuele Orazi, Gianfranco Pradisi
In this review, a pedagogical introduction to the concepts of slow-roll inflationary Universe and number of -folds is provided. In particular, the differences between the basic…
Einstein-Cartan pseudoscalaron inflation
Alessandro Di Marco, Emanuele Orazi, Gianfranco Pradisi
We study a class of early universe cosmological models based on Einstein-Cartan gravity and including a higher derivative term corresponding to a power of the Holst scalar curvatur…
Conformal Metric-Affine Gravities
Gonzalo J. Olmo, Emanuele Orazi, Gianfranco Pradisi
We revisit the gauge symmetry related to integrable projective transformations in metric-affine formalism, identifying the gauge field of the Weyl (conformal) symmetry as a dynamic…
An infinite class of exact rotating black hole metrics of modified gravity
Victor I. Afonso, Gerardo Mora-Pérez, Gonzalo J. Olmo +2
We build an infinite class of exact axisymmetric solutions of a metric-affine gravity theory, namely, Eddington-inspired Born-Infeld gravity, coupled to an anisotropic fluid as a m…
