Decay of Magnetic Fields in the Early Universe
Mark Hindmarsh, M. Christensson, A. Brandenburg
We study the evolution of a stochastic helical magnetic field generated in the early Universe after the electroweak phase transition, using standard magnetohydrodynamics (MHD). We…
Scaling laws in decaying helical hydromagnetic turbulence
Mattias Christensson, Mark Hindmarsh, Axel Brandenburg
We study the evolution of growth and decay laws for the magnetic field coherence length xi, energy E_M and magnetic helicity H in freely decaying 3D MHD turbulence. We show that wi…
Photon-Axion mixing in an inhomogeneous universe
Mattias Christensson, Malcolm Fairbairn
We consider the dimming of photons from high redshift type 1a supernovae by mixing with a pseudoscalar axion field in the intergalactic medium. We model the electron density using…
MHD inverse cascade in the early Universe
Mark Hindmarsh, M. Christensson, A. Brandenburg
We have carried out numerical simulations of freely decaying magnetohydrodynamic (MHD) turbulence in three dimensions, which can be applied to the evolution of stochastic magnetic…
Inverse cascade in decaying 3D magnetohydrodynamic turbulence
Mattias Christensson, Mark Hindmarsh, Axel Brandenburg
We perform direct numerical simulations of three-dimensional freely decaying magnetohydrodynamic (MHD) turbulence. For helical magnetic fields an inverse cascade effect is observed…
Magnetic fields in the early universe in the string approach to MHD
Mattias Christensson, Mark Hindmarsh
There is a reformulation of magnetohydrodynamics in which the fundamental dynamical quantities are the positions and velocities of the lines of magnetic flux in the plasma, which t…
