Finite Orbital Angular momentum Bessel beams propagating along light-cone coordinates
Felipe A. Asenjo, Swadesh M. Mahajan
New solutions for Bessel electromagnetic beams, propagating along the light cones, are investigated. Of the variety of structures possible in the light cone variables, the one invo…
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…
Electron scale magnetic holes generation driven by Whistler-to-Bernstein mode conversion in fully kinetic plasma turbulence
JoaquÃn Espinoza-Troni, Giuseppe Arrò, Felipe A Asenjo +1
Magnetic holes (MHs) are coherent structures characterized by a strong and localized magnetic field amplitude dip, commonly observed in the solar wind and planetary magnetosheaths.…
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…
Upshifted frequency of electromagnetic plasma waves due to reflecting gravitational waves acting as almost-luminal mirrors
Felipe A. Asenjo, Swadesh M. Mahajan
We show that dispersive gravitational waves, as a background spacetime, can reflect electromagnetic waves in a plasma. This reflection upshifts the frequency of the reflected wave,…
