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…
Affine gravitational scenario for dark matter decay
Hemza Azri, Adil Jueid, Canan Karahan +1
Since the current evidence of its existence is revealed only through its gravitational influence, the way dark matter couples to gravity must be then of primary importance. Here, u…
Entropy Production in Affine Inflation
Hemza Azri, Salah Nasri
Multiple scalar fields nonminimally interacting through pure affine gravity are considered to generate primordial perturbations during an inflationary phase. The couplings consider…
Inducing Gravity From Connections and Scalar Fields
Hemza Azri
We propose an approach to induced gravity, or Sakharov's "metrical elasticity", which requires only an affine spacetime that accommodates scalar fields. The setup provides the indu…
