Spacetimes dressed with stealth electromagnetic fields
Ivica Smolić
Stealth field configurations by definition have a vanishing energy-momentum tensor, thus do not contribute to the gravitational field equations. While only trivial fields can be st…

Nonlinear electromagnetic fields and symmetries
Irena Barjašić, Luka Gulin, Ivica Smolić
We extend the classical results on the symmetry inheritance of the canonical electromagnetic fields, described by the Maxwell's Lagrangian, to a much wider class of models, which i…
