Generalised Non-Linear Electrodynamics: classical picture and effective mass generation
Abedennour Dib, José A. Helayël-Neto, Alessandro D. A. M. Spallicci
Starting from a generic Lagrangian, we discuss the number of propagating degrees of freedom in the framework of generalised non-linear electrodynamics when a photon-background spli…
Photon frequency variation in non-linear electro-magnetism
Alessandro D. A. M. Spallicci, Abedennour Dib, José A. Helayël-Neto
We set a generalised non-linear Lagrangian, encompassing Born-Infeld and Heisenberg-Euler theories among others. The Lagrangian reduces to the Maxwell Lagrangian at lowest order. T…
Testing the Ampère-Maxwell law on the photon mass and Lorentz-Poincaré symmetry violation with MMS multi-spacecraft data
Alessandro D. A. M. Spallicci, Giuseppe Sarracino, Orélien Randriamboarison +2
We investigate possible evidence from Extended Theories of Electro-Magnetism by looking for deviations from the Ampère-Maxwell law. The photon, main messenger for interpreting the…
Aspects of Lorentz-Poincaré-symmetry violating physics in a supersymmetric scenario
Patricio Gaete, J. A. Helayël-Neto, Alessandro D. A. M. Spallicci
We study a Lorentz invariance violating extension for the pure photonic sector of the standard model in a supersymmetric scenario. We identify a number of independent background fe…
Frequency variation for in vacuo photon propagation in the Standard-Model Extension
José A. Helayël-Neto, Alessandro D. A. M. Spallicci
In the presence of Lorentz Symmetry Violation (LSV) associated with the Standard-Model Extension (SME), we have recently shown the non-conservation of the energy-momentum tensor 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…
