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…

Planckeons as mouths of quantum wormholes and holographic origin of spacetime
Ignazio Licata, Fabrizio Tamburini, Davide Fiscaletti
We argue that Planck-scale fluctuations ``planckeons'' realize a network of non-traversable Einstein--Rosen bridges and act as holographic devices. Modeling planckeons as wormhole…
