Isocurvature modes and non-Gaussianity in affine inflation
Hemza Azri, Isaac Bamwidhi, Salah Nasri
Inflationary dynamics driven by multiple fields, especially with nonminimal couplings, allow for highly interesting features such as isocurvature, non-Gaussianity, and preheating.…
Ricci-Determinant Gravity: Dynamical Aspects and Astrophysical Implications
Hemza Azri, K. Yavuz Ekşi, Canan Karahan +1
The Palatini gravitational action is enlarged by an arbitrary function of the determinants of the Ricci tensor and the metric, . The res…
Dynamical aspects of asymmetric Eddington gravity with scalar fields
Hemza Azri, Salah Nasri
In Eddington gravity, the action principle involves only the symmetric parts of the connection and the Ricci tensor, with a metric that emerges proportionally to the latter. Here,…
Scalar-Connection Gravity and Spontaneous Scalarization
Hemza Azri, Salah Nasri
Scalar-tensor theories of gravity are known to allow significant deviations from general relativity through various astrophysical phenomena. In this paper, we formulate a scalar-co…
