Evolution of hydromagnetic turbulence from the electroweak phase transition
Axel Brandenburg, Tina Kahniashvili, Sayan Mandal +3
We present new simulations of decaying hydromagnetic turbulence for a relativistic equation of state relevant to the early universe. We compare helical and nonhelical cases either…
The observational constraints on the flat CDM models
Olga Avsajanishvili, Yiwen Huang, Lado Samushia +1
Most dark energy models have the CDM as their limit, and if future observations constrain our universe to be close to CDM Bayesian arguments about the evidence and the fine-t…
The dynamo effect in decaying helical turbulence
Axel Brandenburg, Tina Kahniashvili, Sayan Mandal +3
We show that in decaying hydromagnetic turbulence with initial kinetic helicity, a weak magnetic field eventually becomes fully helical. The sign of magnetic helicity is opposite t…
The turbulent chiral-magnetic cascade in the early universe
Axel Brandenburg, Jennifer Schober, Igor Rogachevskii +5
The presence of asymmetry between fermions of opposite handedness in plasmas of relativistic particles can lead to exponential growth of a helical magnetic field via a small-scale…
