Equivalence Principle violation in metric-affine gravity and finite-temperature effects
Emmanuele Battista, Roberto Campagnola, Salvatore Capozziello +1
Possible violations of the equivalence principle are investigated within the framework of metric-affine gravity and their connection to finite-temperature effects are highlighted.…
Extrinsic geometry and Hamiltonian analysis of symmetric teleparallel gravity
Salvatore Capozziello, Dario Sauro
We analyze the properties of foliations in presence of non-metricity, deriving the generalized Gauss-Codazzi relations in full generality. These results are employed to study the t…
Novel scalar degrees of freedom emerging from hybrid metric-Palatini gravity
David S. Pereira, Salvatore Capozziello, Francisco S. N Lobo +1
Hybrid metric-Palatini gravity unifies the metric and Palatini formalisms while preserving a propagating scalar degree of freedom, offering a compelling route to modified gravity c…
Stable black holes in lower dimensional non-metric gravity
G. G. L. Nashed, Salvatore Capozziello
We investigate exact charged and uncharged black hole solutions in a (2+1)-dimensional spacetime within the framework of quadratic form of symmetric teleparallel gr…
Non-local Metric-Affine Gravity
Salvatore Capozziello, Damianos Iosifidis
Non-local gravity can potentially solve several problems of gravitational field both at Ultra-Violet and Infra-Red scales. However, such an approach has been formulated mainly in m…
Comparing Inflationary Models in Extended Metric-Affine Theories of Gravity
Salvatore Capozziello, Mehdi Shokri
We study slow-roll inflation as a common feature in Metric-affine Theories of Gravity. In particular, we take into account extended metric, teleparallel and symmetric-teleparallel…
