Transport coefficients in the early universe
Jarkko Ahonen
We calculate numerically the electrical conductivity , heat conductivity and shear viscosity of the hot plasma present in the early universe for the temperature interval…
Magnetic field generation in first order phase transition bubble collisions
Jarkko Ahonen, Kari Enqvist
We consider the formation of a ring-like magnetic field in collisions of bubbles of broken phase in an abelian Higgs model. Particular attention is paid on multiple collisions. The…
Electrical conductivity in the early universe
Jarkko Ahonen, Kari Enqvist
We solve numerically the Boltzmann equation in the early universe in the presence of a constant electric field and find the electrical conductivity in the range $1\MeV\lsim T\l…
The paradox of axions surviving primordial magnetic fields
Jarkko Ahonen, Kari Enqvist, Georg Raffelt
In the presence of primordial magnetic fields the oscillating cosmic axion field drives an oscillating electric field. The ensuing dissipation of axions is found to be inversely pr…
