Generation of Gravitational Radiation in Dusty Plasmas and Supernovae
G. Brodin, M. Marklund, P. K. Shukla
We present a novel nonlinear mechanism for exciting a gravitational radiation pulse (or a gravitational wave) by dust magnetohydrodynamic (DMHD) waves in dusty astrophysical plasma…
A possibility to measure elastic photon--photon scattering in vacuum
Daniel Eriksson, Gert Brodin, Mattias Marklund +1
Photon--photon scattering in vacuum due to the interaction with virtual electron-positron pairs is a consequence of quantum electrodynamics. A way for detecting this phenomenon has…
The general relativistic MHD dynamo equation
Mattias Marklund, Chris Clarkson
The magnetohydrodynamic dynamo equation is derived within general relativity, using the covariant 1+3 approach, for a plasma with finite electric conductivity. This formalism allow…
A new electromagnetic wave in a pair plasma
Lennart Stenflo, Gert Brodin, Mattias Marklund +1
A new nonlinear electromagnetic wave mode in a plasma is reported. Its existence depends on the interaction of an intense circularly polarized electromagnetic wave with a plasma, w…
Quantum electrodynamical modes in pair plasmas
Mattias Marklund, Padma K. Shukla, Gert Brodin +1
We predict the existence of new nonlinear electromagnetic wave modes in pair plasmas. The plasma may be either non-magnetized or immersed in an external magnetic field. The existen…
The Intense Radiation Gas
M. Marklund, P. K. Shukla, B. Eliasson
We present a new dispersion relation for photons that are nonlinearly interacting with a radiation gas of arbitrary intensity due to photon-photon scattering. It is found that the…
