Singularities in General Relativity coupled to nonlinear electrodynamics
M. Novello, S. E. Perez Bergliaffa, J. M. Salim
We study here some consequences of the nonlinearities of the electromagnetic field acting as a source of Einstein's equations on the propagation of photons. We restrict to the part…
A nongravitational wormhole
F. Baldovin, M. Novello, S. E. Perez Bergliaffa +1
Using the effective metric formalism for photons in a nonlinear electromagnetic theory, we show that a certain field configuration in Born-Infeld electromagnetism in flat spacetime…
Electromagnetic waves in a wormhole geometry
S. E. Perez Bergliaffa, K. E. Hibberd
We investigate the propagation of electromagnetic waves through a static wormhole. It is shown that the problem can be reduced to a one-dimensional Schrödinger-like equation with a…
