The Axion-Photon Mixing and the Extragalactic Magnetic Background: Plateau Regimes, Resonances, and Non-Gaussian Boosts
Andrea Addazi, Yi-Fu Cai, Salvatore Capozziello +2
We present an analytical treatment of Axion-Like-Particle (ALP)--photon mixing with extragalactic background light (EBL) attenuation for constant, Gaussian-stochastic, and non-Gaus…
Equivalent Gravities and Equivalence Principle: Foundations and experimental implications
Christian Mancini, Guglielmo Maria Tino, Salvatore Capozziello
The so-called Geometric Trinity of Gravity includes General Relativity (GR), based on spacetime curvature; the Teleparallel Equivalent of GR (TEGR), which relies on spacetime torsi…
Extended Geometric Trinity of Gravity
Salvatore Capozziello, Sara Cesare, Carmen Ferrara
Extensions of equivalent representations of gravity are discussed in the metric-affine framework. First, we focus on: (i) General Relativity, based upon the metric tensor whose dyn…
The Equivalence Principle as a Noether Symmetry
Salvatore Capozziello, Carmen Ferrara
The Equivalence Principle is considered in the framework of metric-affine gravity. We show that it naturally emerges as a Noether symmetry starting from a general non-metric theory…
