The flexibility of optical metrics
Eduardo Bittencourt, Jonas P. Pereira, Igor Smolyaninov +1
We firstly revisit the importance, naturalness and limitations of the so-called optical metrics for describing the propagation of light rays in the limit of geometric optics. We th…
Energy decomposition within Einstein-Born-Infeld black holes
Jonas P. Pereira, Jorge A. Rueda
We analyze the consequences of the recently found generalization of the Christodoulou-Ruffini black hole mass decomposition for Einstein-Born-Infeld black holes [characterized by t…
Multirefringence phenomena in nonlinear electrodynamics
Vitorio A. De Lorenci, Renato Klippert, Shi-Yuan Li +1
Wave propagation in nonlinear theories of the electromagnetism described by Lagrangian densities dependent upon its two local invariants L(F, G) is revisited. On the light of the r…
Radial stability in stratified stars
Jonas P. Pereira, Jorge A. Rueda
We formulate within a generalized distributional approach the treatment of the stability against radial perturbations for both neutral and charged stratified stars in Newtonian and…
Stability of thin-shell interfaces inside compact stars
Jonas P. Pereira, Jaziel G. Coelho, Jorge A. Rueda
We use the thin-shell Darmois-Israel formalism to model and assess the stability of the interfaces separating phases, e.g. the core and the crust, within compact stars. We exemplif…
