Relativistic viscous effects on the primordial gravitational waves spectrum
Nahuel Mirón-Granese
We study the impact of the viscous effects of the primordial plasma on the evolution of the primordial gravitational waves (pGW) spectrum from Inflation until today, considering a…

On the phase space in Double Field Theory
Eric Lescano, Nahuel Mirón-Granese
We present a model of (double) kinetic theory which paves the way to describe matter in a Double Field Theory background. Generalized diffeomorphisms acting on double phase space t…

Nonlinear Fluctuations in Relativistic Causal Fluids
Nahuel Mirón-Granese, Alejandra Kandus, Esteban Calzetta
In the Second Order Theories (SOT) of real relativistic fluids, the non-ideal properties of the flows are described by a new set of dynamical tensor variables. In this work we expl…
