Perfect magnetohydrodynamics as a field theory
Jacob D. Bekenstein, Gerold Betschart
We propose the generally covariant action for the theory of a self-coupled complex scalar field and electromagnetism which by virtue of constraints is equivalent, in the regime of…

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…
