Primordial turbulence from inflation: a new inflaton-driven turbulent regime
Oksana Iarygina, Axel Brandenburg
For the first time, we establish a direct connection between inflationary dynamics and the subsequent magnetohydrodynamic evolution. Starting from vacuum fluctuations, we self-cons…
Isochrones in primordial magnetic field evolution
Axel Brandenburg, Mattia Cielo, Oksana Iarygina +1
In the early universe, a primordial magnetic field undergoes a turbulent decay while its length scale increases due to an inverse cascade. The size of the largest processed eddy sc…
Ultra slow-turn inflation
Ana Achúcarro, Perseas Christodoulidis, Jinn-Ouk Gong +1
In standard multi-field models, tachyonic isocurvature perturbations generally indicate the presence of an instability. We revisit the stability of some known counterexamples and s…
