Electromagnetic plasma wave modes propagating along light-cone coordinates
Felipe A. Asenjo, Swadesh M. Mahajan
We present new electromagnetic plasma wavepacket solutions that propagates in one time and one space coordinates. Differently to the usual plane wave solution, which is written in…
The effect of plasma expansion on the dispersion properties of MHD waves
Sebastián Saldivia, Felipe A. Asenjo, Pablo S. Moya
In this work, we employ the set of ideal expanding magnetohydrodynamic (MHD) equations within the Expanding Box Model (EBM) framework to theoretically characterize the effects of r…
Dark energy as a battery for magnetic field generation in plasmas
Nicolás Villarroel-Sepúlveda, Pablo S. Moya, Felipe A. Asenjo +1
It is shown that in the spacetime dominated by a cosmological constant, in the far region of a Schwarzschild-de Sitter black hole, a seed magnetic field can be generated in an ambi…
Different kinds of accelerated propagation of relativistic electromagnetic plasma wavepackets
Felipe A. Asenjo
Relativistic electromagnetic plasma waves are described by a dynamical equation that can be solved not only in terms of plane waves, but for several different accelerating wavepack…
