Bounds on screened dark energy from near-Earth space-based measurements
Fabiano Feleppa, Welmoed Marit de Graaf, Philippe Brax +1
We test screened dark energy with near-Earth, space-based measurements. In a post-Newtonian framework, we compute leading corrections to geodetic precession (Gravity Probe B), LAGE…

Imprints of screened dark energy on nonlocal quantum correlations
Fabiano Feleppa, Gaetano Lambiase, Sunny Vagnozzi
We investigate how screening mechanisms, reconciling light scalar fields driving cosmic acceleration with local fifth force constraints, can be probed via their impact on non-local…

Charge constraint on M87* with twisted light
Fabiano Feleppa, Fabrizio Tamburini, Gaetano Lambiase
We propose a novel method to constrain the electric charge of the supermassive black hole M87* by analyzing the orbital angular momentum content of the light it emits. By leveragin…
