Extended Theories of Electrodynamics in Gravity
Francesco Bajardi, Micol Benetti, Salvatore Capozziello +1
Within the general framework of gravity, we introduce a function of the electromagnetic curvature invariant that couples minimally to gravitation to ensure a…

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…

Generalised Aichelburg-Sexl and Self-Force for photons
Abedennour Dib, Aymeric Garnier, Alessandro Spallicci
We generalise the Aichelburg-Sexl Stress-Energy-Momentum tensor for massless particles to include motion with angular velocity, introducing tensorial spherical harmonics. Further,…
