Magnetic Connections in Curved Spacetime
Felipe A. Asenjo, Luca Comisso
The ideal MHD theorem on the conservation of the magnetic connections between plasma elements is generalized to relativistic plasmas in curved spacetime. The connections between pl…
A differential geometry approach to asymmetric transmission of light
Felipe A. Asenjo, Cristián Erices, Andrés Gomberoff +2
In the last ten years, the technology of differential geometry, ubiquitous in gravitational physics, has found its place in the field of optics. It has been successfully used in th…
New non-linear modified massless Klein--Gordon equation
Felipe A. Asenjo, Sergio A. Hojman
The massless Klein--Gordon equation on arbitrary curved backgrounds allows for solutions which develop "tails" inside the light cone and, therefore, do not strictly follow null geo…
Birefringent light propagation on anisotropic cosmological backgrounds
Felipe A. Asenjo, Sergio A. Hojman
Exact electromagnetic wave solutions to Maxwell equations on anisotropic Bianchi I cosmological spacetime backgrounds are studied. The waves evolving on Bianchi I spacetimes exhibi…
Fully relativistic kinetic equation for spin-1/2 particles in the long scale-length approximation
Robin Ekman, Felipe A. Asenjo, Jens Zamanian
In this paper we derive a fully relativistic kinetic theory for spin-1/2 particles and its coupling to Maxwell's equations, valid in the long scale-length limit, where the fields v…
Relativistic Magnetic Reconnection in Kerr Spacetime
Felipe A. Asenjo, Luca Comisso
The magnetic reconnection process is analyzed for relativistic magnetohydrodynamical plasmas around rotating black holes. A simple generalization of the Sweet-Parker model is used…
