Relativistic Chiral MHD with application to the early Universe
Deepen Garg, Jennifer Schober
We present a systematic derivation of the equations of relativistic chiral magnetohydrodynamics (MHD) for a plasma of charged fermions in an expanding universe. Through a combinati…
A charge-flow instability in plasmas with charge fluctuations
Deepen Garg, Jennifer Schober
We present a linear instability in magnetized plasmas with charge fluctuations. It is driven by an electric current proportional to the charge chemical potential and the bulk v…
Are magnetic fields in cosmic voids primordial?
Deepen Garg, Ruth Durrer, Jennifer Schober
The nature of magnetic fields in the voids of the large-scale structure of the Universe has been a multifaceted open puzzle for decades. On one hand, their origin is not clear with…
Scalar perturbations from inflation in the presence of gauge fields
R. Durrer, R. von Eckardstein, Deepen Garg +3
We study how Abelian-gauge-field production during inflation affects scalar perturbations in the case when the gauge field interacts with the inflaton directly (by means of generic…
