Quantum field approach to relativistic turbulence
Esteban Calzetta
The goal of this work is apply field theory methods to discuss turbulence in relativistic real fluids. We shalltake as representtive model an Israel-Stewart framework, where the co…

Hydrodynamic models of reheating
Juan Pablo ElÃa, Lucas Cantarutti, Nahuel Mirón-Granese +1
We develop a causal hydrodynamic model that provides an effective macroscopic description of the field-theoretic dynamics during the early stages of reheating. The inflaton condens…

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…
