The Turbulent Chiral Magnetic Cascade in the Early Universe Academic Article uri icon

abstract

  • Abstract 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 chiral dynamo instability known as the chiral magnetic effect. Here, we show, using dimensional arguments and numerical simulations, that this process produces through the Lorentz force chiral magnetically driven turbulence. A ${k}^{-2} $ magnetic energy spectrum emerges via inverse transfer over a certain range of wavenumbers k. The total chirality …
