Response to ``Comment on `Primordial magnetic seed field amplification by gravitational waves' "
G. Betschart, C. Zunkel, P. K. S. Dunsby +1
Here we respond to the comment by Tsagas (gr-qc/0503042) on our paper gr-qc/0503006. We show that the results in that comment are flawed and cannot be used for drawing conclusion a…
Graviton mediated photon-photon scattering in general relativity
G. Brodin, D. Eriksson, M. Marklund
In this paper we consider photon-photon scattering due to self-induced gravitational perturbations on a Minkowski background. We focus on four-wave interaction between plane waves…
Nonlinear Interactions Between Gravitational Radiation and Modified Alfven Modes in Astrophysical Dusty Plasmas
Mats Forsberg, Gert Brodin, Mattias Marklund +2
We present an investigation of nonlinear interactions between Gravitational Radiation and modified Alfvén modes in astrophysical dusty plasmas. Assuming that stationary charged dus…
On inhomogeneous magnetic seed fields and gravitational waves within the MHD limit
Caroline Zunckel, Gerold Betschart, Peter K S Dunsby +1
In this paper we apply second-order gauge-invariant perturbation theory to investigate the possibility that the non-linear coupling between gravitational waves (GW) and a large sca…
Primordial magnetic seed field amplification by gravitational waves
Gerold Betschart, Caroline Zunckel, Peter Dunsby +1
Using second-order gauge-invariant perturbation theory, a self-consistent framework describing the non-linear coupling between gravitational waves and a large-scale homogeneous mag…
Photon-graviton pair conversion
A. Kallberg, G. Brodin, M. Marklund
We consider the conversion of gravitons and photons as a four-wave mixing process. A nonlinear coupled systems of equations involving two gravitons and two photons is obtained, and…
