Primordial gravitational waves amplification from causal fluids
N Miron-Granese, E Calzetta - Physical Review D, 2018 - APS
We consider the evolution of the gravitational wave spectrum for super-Hubble modes in
interaction with a relativistic fluid, which is regarded as an effective description of fluctuations …

Primordial weibel instability
N Mirón-Granese, E Calzetta… - Journal of Cosmology and …, 2022 - iopscience.iop.org
We study the onset of vector instabilities in the post-inflationary epoch of the Universe as a
mechanism for primordial magnetic fields amplification. We assume the presence of a …

Causal relativistic hydrodynamics of conformal Fermi-Dirac gases
M Aguilar, E Calzetta - Physical Review D, 2017 - APS
In this paper we address the derivation of causal relativistic hydrodynamics, formulated
within the framework of divergence type theories (DTTs), from kinetic theory for spinless …
