Vacuum Cherenkov radiation in supercritical magnetic fields
Daniel Gálvez-García, Nora Bretón
In the presence of very intense electromagnetic fields, the refractive index of vacuum is modified such that light velocity is less than and ultrarelativistic charged particles…
Remarks on electrical Penrose process for magnetized Reissner-Nordström black hole
A. Baez, Nora Breton, I. Cabrera-Munguia
The energy extraction from a magnetized Reissner-Nordström black hole is analyzed within the framework of the electric Penrose mechanism. The presence of an external magnetic field…
Birefringence and QuasiNormal Modes of the Einstein-Euler-Heisenberg Black Hole
Nora Bretón, L. A. López
In this contribution we study the birefringence and the quasinormal modes (QNM) in the eikonal approximation, of the Einstein-Euler-Heisenberg black hole (EEH-BH) . The EEH-BH is a…
Thermodynamics of the Euler-Heisenberg-AdS black hole
Daniela Magos, Nora Bretón
We generalize the solution to the Euler-Heisenberg (EH) theory coupled to gravity that represents a nonlinearly charged static black hole (BH) introducing the cosmological constant…
Aspects of the BTZ black hole interacting with fields
Leonardo Ortíz, Nora Bretón
We show that there is no superradiance for the Dirac field in the rotating BTZ black hole if the field vanishes at infinity. Then we outline the calculation of the expression for t…
On the NUT-Born-Infeld- spacetime
Nora Bretón, C. E. Ramírez-Codiz
The stationary axisymmetric spacetime coupled to nonlinear Born-Infeld electrodynamics is studied. The solution was derived by Plebanski et al (1984) and it is characterized by six…
