Emergence of Gravity's Dynamical and Topological Sectors from Pre-geometry

Andrea Addazi, Giuseppe Meluccio

We identify the complete set of fundamental building blocks for a 4D pre-geometric theory of gravity. Based on a gauge theory of or coupled to a Higgs-like fiel…

Energy conditions in static, spherically symmetric spacetimes and effective geometries

Zi-Liang Wang, Emmanuele Battista

Classical energy conditions are investigated in generic static and spherically symmetric spacetimes. In setups with nonconstant , the appearance of horizons can sign…

Minisuperspace Cosmology in Extended Geometric Trinity of Gravity

Emmanuele Battista, Salvatore Capozziello, Stefano Pastore

We investigate Extended Geometric Trinity of Gravity at both classical and quantum cosmological levels using the minisuperspace approach. Adopting Noether symmetries to select viab…

Shadow signatures and energy accumulation in Lorentzian-Euclidean black holes

Emmanuele Battista, Salvatore Capozziello, Che-Yu Chen

The Lorentzian-Euclidean black hole has been recently introduced as a geodesically complete spacetime featuring a signature shift at the event horizon where causal geodesics are pr…

(Lovelock) inflation: explaining the ACT data and equivalence to Higgs-Gauss-Bonnet inflation

Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +1

We revisit the Starobinsky model of inflation in light of recent data from the Atacama Cosmology Telescope (ACT), which indicates a potential preference for a slightly larger scala…
