Photon sector analysis of Super and Lorentz symmetry breaking: effective photon mass, bi-refringence and dissipation
Luca Bonetti, Luís R. dos Santos Filho, José A. Helayël-Neto +1
Within the Standard Model Extension (SME), we expand our previous findings on four classes of violations of Super-Symmetry (SuSy) and Lorentz Symmetry (LoSy), differing in the hand…
FRB 121102 Casts New Light on the Photon Mass
Luca Bonetti, John Ellis, Nikolaos E. Mavromatos +3
The photon mass, , can in principle be constrained using measurements of the dispersion measures (DMs) of fast radio bursts (FRBs), once the FRB redshifts are known. The DM of…
Electromagnetic shift arising from the Heisenberg-Euler dipole
Luca Bonetti, Santiago E. Perez Bergliaffa, Alessandro D. A. M. Spallicci
We show that photons may be redshifted or blueshifted when interacting with the field of an overcritical dipole, which incorporates the one-loop QED corrections coming from vacuum…
Entropy theorems in classical mechanics, general relativity, and the gravitational two-body problem
Marius Oltean, Luca Bonetti, Alessandro D. A. M. Spallicci +1
In classical Hamiltonian theories, entropy may be understood either as a statistical property of canonical systems, or as a mechanical property, that is, as a monotonic function of…
Massive photons from Super and Lorentz symmetry breaking
Luca Bonetti, Luís R. dos Santos Filho, José A. Helayël-Neto +1
In the context of Standard Model Extensions (SMEs), we analyse four general classes of Super Symmetry (SuSy) and Lorentz Symmetry (LoSy) breaking, leading to {observable} imprints…
Dispersion by pulsars, magnetars, fast radio bursts and massive electromagnetism at very low radio frequencies
Mark J. Bentum, Luca Bonetti, Alessandro D. A. M. Spallicci
Our understanding of the universe relies mostly on electromagnetism. As photons are the messengers, fundamental physics is concerned in testing their properties. Photon mass upper…
Photon Mass Limits from Fast Radio Bursts
Luca Bonetti, John Ellis, Nikolaos E. Mavromatos +3
The frequency-dependent time delays in fast radio bursts (FRBs) can be used to constrain the photon mass, if the FRB redshifts are known, but the similarity between the frequency d…
Vacuum fluctuation of conformally coupled scalar field in FLRW space-times
Giovanni Acquaviva, Luca Bonetti, Luciano Vanzo +1
The regularized vacuum fluctuation related to a conformally coupled massless scalar field defined on a space-time with dynamical horizon is computed with respect a radially moving…
Ray tracing in FLRW flat space-times
Giovanni Acquaviva, Luca Bonetti, Guido Cognola +1
In this work we take moves from the debate triggered by Melia et al [9]. and followed by opposite comments by Lewis and Oirschot [10,11]. The point in question regards the role of…
