Propagation speeds of relativistic conformal fluids from a generalized relaxation time approximation
Esteban Calzetta, Alejandra Kandus
We compute the propagation speeds for a conformal real relativistic fluid. We begin from a kinetic equation in the relaxation time approximation, where the relaxation time is an ar…

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…
