Description

We extend the derivation of second-order relativistic viscous hydrodynamics to incorporate the effects of baryon current, a non-vanishing chemical potential, and a realistic equation of state. Starting from a microscopic quantum theory, we build a quasiparticle approximation to describe the evolution of hydrodynamic degrees of freedom, highlighting its connection to the Wigner formalism. We perform a second-order hydrodynamic expansion to derive a closed set of equations for the components of the stress-energy tensor and the baryon current.
