Stellar Bounds on a Model with Photon-Photino Oscillation
Bernard Teles de Menezes, José Abdalla Helayël-Neto
In this paper, we pursue an investigation of the consequences of a mixing between supersymmetric partners - the photon and photino - analogous to the so-called Primakoff effect, bu…
Classical investigations in a CPT-even Lorentz-violating model and their implications for the Compton effect
E. Neres Júnior, J. C. C. Felipe, A. P. Baêta Scarpelli +2
In this work, we investigate some aspects of the Maxwell electrodynamics with the additive Lorentz-violating (LV) CPT-even term. For this model, we derive the energy and momentum c…
Green's functions under magnetic effects in a nontrivial topology
Emerson B. S Corrêa, Michelli S. R. Sarges, José A. Helayël-Neto
We calculate the Bose and Dirac field propagators in a four-dimensional Euclidean space under a magnetic external field by using a hybrid version of the Ritus and Schwinger methods…
Non-local material vacuum and Cherenkov radiation in non-linear massive D-Electrodynamics
Patricio Gaete, J. A. Helayël-Neto
We examine the effects of electromagnetic field non-linearities in space-time dimensions. We focus on how these non-linearities influence permittivity and susceptibility. This,…
Loop Quantum Gravity effects on electromagnetic properties of charged leptons
João Paulo S. Melo, Mario J. Neves, Jefferson M. A. Paixão +1
The efforts in this contribution consist in reassessing a modified Dirac equation that incorporates a -Lorentz-symmetry violating (LSV) term induced as a Loop Quantum Grav…
A Dirac-material-inspired non-linear electrodynamic model
M. J. Neves, Patricio Gaete, L. P. R. Ospedal +1
We propose and study the properties of a non-linear electrodynamics that emerges inspired on the physics of Dirac materials. This new electrodynamic model is an extension of the on…
