X-ray pulsed light curves of highly compact neutron stars as probes of scalar-tensor theories of gravity
Tulio Ottoni, Jaziel G. Coelho, Rafael C. R. de Lima +2
The strong gravitational potential of neutron stars (NSs) makes them ideal astrophysical objects for testing extreme gravity phenomena. We explore the potential of NS X-ray pulsed…
Probing nonlinear electrodynamics in slowly rotating spacetimes through neutrino astrophysics
Herman J. Mosquera Cuesta, Gaetano Lambiase, Jonas P. Pereira
Huge electromagnetic fields are known to be present during the late stages of the dynamics of supernovae. Thus, when dealing with electrodynamics in this context, the possibility m…
Magnetic liquids under high electric fields as optical diodes
Jonas P. Pereira, Igor I. Smolyaninov, Vera N. Smolyaninova
We show and give examples of how unidirectional propagation of light rays in the limit of geometric optics could arise in some magnetic fluids due to the magnetoelectric effect und…
Satellite Test of the Equivalence Principle as a Probe of Modified Newtonian Dynamics
Jonas P. Pereira, James M. Overduin, Alexander J. Poyneer
The proposed Satellite Test of the Equivalence Principle (STEP) will detect possible violations of the Weak Equivalence Principle by measuring relative accelerations between test m…
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…
One-way propagation of light in Born-Infeld-like metamaterials
Vitorio A. De Lorenci, Jonas P. Pereira
We propose and investigate a family of nonlinear metamaterials in which light rays propagate just in one direction -- one-way propagation. Furthermore, we argue how such nonlinear…
